fix: handle empty JSON responses in sdk client

[seekskyworld]

Issue link:

• FixesError: Unexpected end of JSON input #8014
• Error: Unexpected end of JSON input #8014

Summary:

• Handle empty JSON responses by falling back to {} instead of throwing.
• Apply the fix to v1/v2 generated clients and keep it via the SDK build patch.

Motivation:

• Some endpoints can return empty bodies, which currently triggers Unexpected end of JSON input in the desktop app.

Validation:

• bun run typecheck (packages/sdk/js)

@seekskyworld this will be fixed upstream hey-api/hey-api#3202

[seekskyworld]

ok

[mrlubos]

@seekskyworld the JSON issue was fixed in v1.1.24, can you try and let me know if this pull request is still needed?

[seekskyworld]

@mrlubos Thanks! I checked v1.1.24 and the v2 SDK now handles empty JSON responses (reads response.text() and parses only
when non‑empty). The issue no longer repros for v2, so this PR seems unnecessary; happy to close unless you still
want coverage for the v1 SDK.

[mrlubos]

@seekskyworld while it would be nice, I assume they don't maintain v1 anymore as I can't see the build script for it. Let me know if you run into any other issues with OpenCode SDKs! I work on the tooling behind them, so this bug is on me

[seekskyworld]

@mrlubos Thanks, that makes sense! I’ll close this PR. I do have a few other PRs that have been waiting for review—could you
take a look when you have a chance and let me know if anything is blocking?
