Updates VQS version inside world-vercel

Note this also moves to the new default visibilityTimeout (30s) and visibilityRefreshInterval (10s)

@VaguelySerious@claude
feat(world-vercel): update to use VQS v3 API
e0c87bd
- Update basePath from /queues/v2/messages to /queues/v3
- Include @vercel/queue tarball with v3 client changes
- Add pnpm override to use bundled tarball
The @vercel/queue client has been updated to:
- Use v3 URL structure (topic and consumer in path)
- Use receiptHandle instead of ticket
- Support both v2 and v3 header names for backwards compat

fix(world-vercel): use cgowrie/v3-client and correct basePath
d022783
- Use cgowrie/v3-client branch which has full v3 implementation
- Update basePath to /queues/v3/queues (matches new client default)

fix(world-vercel): correct basePath from v3/queues to v3/topic
2f5832b
VQS v3 uses /api/v3/topic/{topic} URL pattern instead of /api/v3/queues.

🔧 Build Fix:

Type mismatch between two versions of @ai-sdk/provider library (v3.0.4 and v2.0.0) causing TypeScript compilation errors. The SharedV2ProviderMetadata type from v3.0.4 is incompatible with the v2.0.0 version expected by the codebase.

fix(world-vercel): update @vercel/queue tarball with multipart/mixed fix
c411180
The receiveMessageById method was sending Accept: application/json which
the V3 server rejects. Updated tarball includes the fix to use
Accept: multipart/mixed and proper multipart response parsing.
Also cleaned up duplicate tarball from packages/ directory.

🔧 Build Fix:

The function parameter at line 130 is incompatible with the CallbackHandlers type. The default property returns Promise<void | { timeoutSeconds: number; }> but the handler must return only void | Promise<void>.

Additional Suggestion:

Type mismatch between message handler callback return type and @vercel/queue v3 API's MessageHandler type causes TypeScript compilation error

🔧 Build Fix:

The TypeScript code uses delaySeconds property on QueueOptions type, but this property is not defined in the QueueOptions interface. This causes TypeScript compilation to fail.

The property delaySeconds does not exist on the QueueOptions type. The code is trying to access and use a property that is not defined in the type definition.

this needs to be overrideable by options (so that resumeHook can enqueue messages against a different deployment). the same way queue accepts an option to override this

I don't think postgres does? Either way can add separately - it'll be nice to land this directly to bugbash together with event sourcing

Updates VQS version inside world-vercel
Note this also moves to the new default visibilityTimeout (30s) and visibilityRefreshInterval (10s)
@VaguelySerious@claude
feat(world-vercel): update to use VQS v3 API
e0c87bd
- Update basePath from /queues/v2/messages to /queues/v3
- Include @vercel/queue tarball with v3 client changes
- Add pnpm override to use bundled tarball
The @vercel/queue client has been updated to:
- Use v3 URL structure (topic and consumer in path)
- Use receiptHandle instead of ticket
- Support both v2 and v3 header names for backwards compat

fix(world-vercel): use cgowrie/v3-client and correct basePath
d022783
- Use cgowrie/v3-client branch which has full v3 implementation
- Update basePath to /queues/v3/queues (matches new client default)

fix(world-vercel): correct basePath from v3/queues to v3/topic
2f5832b
VQS v3 uses /api/v3/topic/{topic} URL pattern instead of /api/v3/queues.

🔧 Build Fix:
Type mismatch between two versions of @ai-sdk/provider library (v3.0.4 and v2.0.0) causing TypeScript compilation errors. The SharedV2ProviderMetadata type from v3.0.4 is incompatible with the v2.0.0 version expected by the codebase.

fix(world-vercel): update @vercel/queue tarball with multipart/mixed fix
c411180
The receiveMessageById method was sending Accept: application/json which
the V3 server rejects. Updated tarball includes the fix to use
Accept: multipart/mixed and proper multipart response parsing.
Also cleaned up duplicate tarball from packages/ directory.

🔧 Build Fix:
The function parameter at line 130 is incompatible with the CallbackHandlers type. The default property returns Promise<void | { timeoutSeconds: number; }> but the handler must return only void | Promise<void>.

🔧 Build Fix:
The TypeScript code uses delaySeconds property on QueueOptions type, but this property is not defined in the QueueOptions interface. This causes TypeScript compilation to fail.

this needs to be overrideable by options (so that resumeHook can enqueue messages against a different deployment). the same way queue accepts an option to override this

@VaguelySerious@claude
feat(world-vercel): update to use VQS v3 API
e0c87bd
- Update basePath from /queues/v2/messages to /queues/v3
- Include @vercel/queue tarball with v3 client changes
- Add pnpm override to use bundled tarball
The @vercel/queue client has been updated to:
- Use v3 URL structure (topic and consumer in path)
- Use receiptHandle instead of ticket
- Support both v2 and v3 header names for backwards compat

fix(world-vercel): use cgowrie/v3-client and correct basePath
d022783
- Use cgowrie/v3-client branch which has full v3 implementation
- Update basePath to /queues/v3/queues (matches new client default)

@VaguelySerious@claude
fix(world-vercel): correct basePath from v3/queues to v3/topic
2f5832b
VQS v3 uses /api/v3/topic/{topic} URL pattern instead of /api/v3/queues.

🔧 Build Fix:
Type mismatch between two versions of @ai-sdk/provider library (v3.0.4 and v2.0.0) causing TypeScript compilation errors. The SharedV2ProviderMetadata type from v3.0.4 is incompatible with the v2.0.0 version expected by the codebase.

@VaguelySerious@claude
fix(world-vercel): update @vercel/queue tarball with multipart/mixed fix
c411180
The receiveMessageById method was sending Accept: application/json which
the V3 server rejects. Updated tarball includes the fix to use
Accept: multipart/mixed and proper multipart response parsing.
Also cleaned up duplicate tarball from packages/ directory.

🔧 Build Fix:
The function parameter at line 130 is incompatible with the CallbackHandlers type. The default property returns Promise<void | { timeoutSeconds: number; }> but the handler must return only void | Promise<void>.

🔧 Build Fix:
The TypeScript code uses delaySeconds property on QueueOptions type, but this property is not defined in the QueueOptions interface. This causes TypeScript compilation to fail.

🔧 Build Fix:
The property delaySeconds does not exist on the QueueOptions type. The code is trying to access and use a property that is not defined in the type definition.

this needs to be overrideable by options (so that resumeHook can enqueue messages against a different deployment). the same way queue accepts an option to override this

I don't think postgres does? Either way can add separately - it'll be nice to land this directly to bugbash together with event sourcing

Updates VQS version inside world-vercel
Note this also moves to the new default visibilityTimeout (30s) and visibilityRefreshInterval (10s)
@VaguelySerious@claude
feat(world-vercel): update to use VQS v3 API
e0c87bd
- Update basePath from /queues/v2/messages to /queues/v3
- Include @vercel/queue tarball with v3 client changes
- Add pnpm override to use bundled tarball
The @vercel/queue client has been updated to:
- Use v3 URL structure (topic and consumer in path)
- Use receiptHandle instead of ticket
- Support both v2 and v3 header names for backwards compat

fix(world-vercel): use cgowrie/v3-client and correct basePath
d022783
- Use cgowrie/v3-client branch which has full v3 implementation
- Update basePath to /queues/v3/queues (matches new client default)

@VaguelySerious@claude
fix(world-vercel): correct basePath from v3/queues to v3/topic
2f5832b
VQS v3 uses /api/v3/topic/{topic} URL pattern instead of /api/v3/queues.

🔧 Build Fix:
Type mismatch between two versions of @ai-sdk/provider library (v3.0.4 and v2.0.0) causing TypeScript compilation errors. The SharedV2ProviderMetadata type from v3.0.4 is incompatible with the v2.0.0 version expected by the codebase.

fix(world-vercel): update @vercel/queue tarball with multipart/mixed fix
c411180
The receiveMessageById method was sending Accept: application/json which
the V3 server rejects. Updated tarball includes the fix to use
Accept: multipart/mixed and proper multipart response parsing.
Also cleaned up duplicate tarball from packages/ directory.

🔧 Build Fix:
The function parameter at line 130 is incompatible with the CallbackHandlers type. The default property returns Promise<void | { timeoutSeconds: number; }> but the handler must return only void | Promise<void>.

🔧 Build Fix:
The TypeScript code uses delaySeconds property on QueueOptions type, but this property is not defined in the QueueOptions interface. This causes TypeScript compilation to fail.

this needs to be overrideable by options (so that resumeHook can enqueue messages against a different deployment). the same way queue accepts an option to override this

I don't think postgres does? Either way can add separately - it'll be nice to land this directly to bugbash together with event sourcing

@VaguelySerious@claude
feat(world-vercel): update to use VQS v3 API
e0c87bd
- Update basePath from /queues/v2/messages to /queues/v3
- Include @vercel/queue tarball with v3 client changes
- Add pnpm override to use bundled tarball
The @vercel/queue client has been updated to:
- Use v3 URL structure (topic and consumer in path)
- Use receiptHandle instead of ticket
- Support both v2 and v3 header names for backwards compat

fix(world-vercel): use cgowrie/v3-client and correct basePath
d022783
- Use cgowrie/v3-client branch which has full v3 implementation
- Update basePath to /queues/v3/queues (matches new client default)

fix(world-vercel): correct basePath from v3/queues to v3/topic
2f5832b
VQS v3 uses /api/v3/topic/{topic} URL pattern instead of /api/v3/queues.

🔧 Build Fix:
Type mismatch between two versions of @ai-sdk/provider library (v3.0.4 and v2.0.0) causing TypeScript compilation errors. The SharedV2ProviderMetadata type from v3.0.4 is incompatible with the v2.0.0 version expected by the codebase.

fix(world-vercel): update @vercel/queue tarball with multipart/mixed fix
c411180
The receiveMessageById method was sending Accept: application/json which
the V3 server rejects. Updated tarball includes the fix to use
Accept: multipart/mixed and proper multipart response parsing.
Also cleaned up duplicate tarball from packages/ directory.

🔧 Build Fix:
The function parameter at line 130 is incompatible with the CallbackHandlers type. The default property returns Promise<void | { timeoutSeconds: number; }> but the handler must return only void | Promise<void>.

The TypeScript code uses delaySeconds property on QueueOptions type, but this property is not defined in the QueueOptions interface. This causes TypeScript compilation to fail.

this needs to be overrideable by options (so that resumeHook can enqueue messages against a different deployment). the same way queue accepts an option to override this

Updates VQS version inside world-vercel
Note this also moves to the new default visibilityTimeout (30s) and visibilityRefreshInterval (10s)
@VaguelySerious@claude
feat(world-vercel): update to use VQS v3 API
e0c87bd
- Update basePath from /queues/v2/messages to /queues/v3
- Include @vercel/queue tarball with v3 client changes
- Add pnpm override to use bundled tarball
The @vercel/queue client has been updated to:
- Use v3 URL structure (topic and consumer in path)
- Use receiptHandle instead of ticket
- Support both v2 and v3 header names for backwards compat

fix(world-vercel): use cgowrie/v3-client and correct basePath
d022783
- Use cgowrie/v3-client branch which has full v3 implementation
- Update basePath to /queues/v3/queues (matches new client default)

@VaguelySerious@claude
fix(world-vercel): correct basePath from v3/queues to v3/topic
2f5832b
VQS v3 uses /api/v3/topic/{topic} URL pattern instead of /api/v3/queues.

🔧 Build Fix:
Type mismatch between two versions of @ai-sdk/provider library (v3.0.4 and v2.0.0) causing TypeScript compilation errors. The SharedV2ProviderMetadata type from v3.0.4 is incompatible with the v2.0.0 version expected by the codebase.

fix(world-vercel): update @vercel/queue tarball with multipart/mixed fix
c411180
The receiveMessageById method was sending Accept: application/json which
the V3 server rejects. Updated tarball includes the fix to use
Accept: multipart/mixed and proper multipart response parsing.
Also cleaned up duplicate tarball from packages/ directory.

🔧 Build Fix:
The function parameter at line 130 is incompatible with the CallbackHandlers type. The default property returns Promise<void | { timeoutSeconds: number; }> but the handler must return only void | Promise<void>.

🔧 Build Fix:
The TypeScript code uses delaySeconds property on QueueOptions type, but this property is not defined in the QueueOptions interface. This causes TypeScript compilation to fail.

this needs to be overrideable by options (so that resumeHook can enqueue messages against a different deployment). the same way queue accepts an option to override this

Updates VQS version inside world-vercel
Note this also moves to the new default visibilityTimeout (30s) and visibilityRefreshInterval (10s)
@VaguelySerious@claude
feat(world-vercel): update to use VQS v3 API
e0c87bd
- Update basePath from /queues/v2/messages to /queues/v3
- Include @vercel/queue tarball with v3 client changes
- Add pnpm override to use bundled tarball
The @vercel/queue client has been updated to:
- Use v3 URL structure (topic and consumer in path)
- Use receiptHandle instead of ticket
- Support both v2 and v3 header names for backwards compat

fix(world-vercel): use cgowrie/v3-client and correct basePath
d022783
- Use cgowrie/v3-client branch which has full v3 implementation
- Update basePath to /queues/v3/queues (matches new client default)

fix(world-vercel): correct basePath from v3/queues to v3/topic
2f5832b
VQS v3 uses /api/v3/topic/{topic} URL pattern instead of /api/v3/queues.

🔧 Build Fix:
Type mismatch between two versions of @ai-sdk/provider library (v3.0.4 and v2.0.0) causing TypeScript compilation errors. The SharedV2ProviderMetadata type from v3.0.4 is incompatible with the v2.0.0 version expected by the codebase.

fix(world-vercel): update @vercel/queue tarball with multipart/mixed fix
c411180
The receiveMessageById method was sending Accept: application/json which
the V3 server rejects. Updated tarball includes the fix to use
Accept: multipart/mixed and proper multipart response parsing.
Also cleaned up duplicate tarball from packages/ directory.

🔧 Build Fix:
The function parameter at line 130 is incompatible with the CallbackHandlers type. The default property returns Promise<void | { timeoutSeconds: number; }> but the handler must return only void | Promise<void>.

The TypeScript code uses delaySeconds property on QueueOptions type, but this property is not defined in the QueueOptions interface. This causes TypeScript compilation to fail.

this needs to be overrideable by options (so that resumeHook can enqueue messages against a different deployment). the same way queue accepts an option to override this

Updates VQS version inside world-vercel
Note this also moves to the new default visibilityTimeout (30s) and visibilityRefreshInterval (10s)
@VaguelySerious@claude
feat(world-vercel): update to use VQS v3 API
e0c87bd
- Update basePath from /queues/v2/messages to /queues/v3
- Include @vercel/queue tarball with v3 client changes
- Add pnpm override to use bundled tarball
The @vercel/queue client has been updated to:
- Use v3 URL structure (topic and consumer in path)
- Use receiptHandle instead of ticket
- Support both v2 and v3 header names for backwards compat

🔧 Build Fix:
Type mismatch between two versions of @ai-sdk/provider library (v3.0.4 and v2.0.0) causing TypeScript compilation errors. The SharedV2ProviderMetadata type from v3.0.4 is incompatible with the v2.0.0 version expected by the codebase.

@VaguelySerious@claude
fix(world-vercel): update @vercel/queue tarball with multipart/mixed fix
c411180
The receiveMessageById method was sending Accept: application/json which
the V3 server rejects. Updated tarball includes the fix to use
Accept: multipart/mixed and proper multipart response parsing.
Also cleaned up duplicate tarball from packages/ directory.

🔧 Build Fix:
The function parameter at line 130 is incompatible with the CallbackHandlers type. The default property returns Promise<void | { timeoutSeconds: number; }> but the handler must return only void | Promise<void>.

🔧 Build Fix:
The TypeScript code uses delaySeconds property on QueueOptions type, but this property is not defined in the QueueOptions interface. This causes TypeScript compilation to fail.

The property delaySeconds does not exist on the QueueOptions type. The code is trying to access and use a property that is not defined in the type definition.

this needs to be overrideable by options (so that resumeHook can enqueue messages against a different deployment). the same way queue accepts an option to override this

I don't think postgres does? Either way can add separately - it'll be nice to land this directly to bugbash together with event sourcing
