Pull request overview
This PR adds automatic retry logic to World operations to improve resilience against transient failures such as network issues and server errors.
- Implements a configurable retry mechanism using the
async-retrypackage with exponential backoff - Creates a proxy-based wrapper that automatically applies retry logic to all World methods
- Defines logic to distinguish retryable errors (network failures, 5xx errors, timeouts) from non-retryable ones (4xx client errors)

🔧 Build Fix:
The withRetry function incorrectly returns the result of calling bail(), which returns void, but the callback signature requires returning a value of type T. The fix is to call bail() without returning it, then throw the error to satisfy the type checker.

Analysis
TypeScript compilation error: bail() return type incompatibility
What fails: TypeScript compiler fails on src/runtime/retry.ts line 126 due to incorrect return type for the bail() function callback.
How to reproduce:
cd packages/core
pnpm run buildResult:
src/runtime/retry.ts(126,3): error TS2322: Type 'void | T' is not assignable to type 'T'.
'T' could be instantiated with an arbitrary type which could be unrelated to 'void | T'.
Root cause: The async-retry library's bail() function has signature (e: Error) => void and does not return a value. However, the code was using return bail(error as Error), which attempts to return void when the function signature requires returning T. The fix calls bail() without returning its result, then throws the error to ensure the correct return type.

This looks fine to solve the immediate issue, assuming we change the update calls to be re-tried too, since those seem pretty important to re-try.
On a higher level, I don't like that we're re-defining the entire interface. Was it not possible to use a JS getter proxy?

What is "AbortError from timeouts" referring to here?

Isn't update idempotent? We should retry IMO

| update: (runId: string, stepId: string, data: UpdateStepRequest) => { | ||

| }, | ||

| // Non-idempotent write - no retry |
