Problem:
- Multiple rapid calls to sendTranscript() created race conditions
- Old requests continued using local abortController variable
- Responses from superseded requests could still be processed
- Session stop didn't reliably prevent pending responses
Solution:
- Changed abort checks from `abortController.signal.aborted` to
`abortControllerRef.current !== abortController`
- Ensures request checks if it's still the active one, not just aborted
- Added checks at 4 critical points: before API call, after API call,
before retry, and after retry
Changes:
- VoiceContext.tsx:268 - Check before initial API call
- VoiceContext.tsx:308 - Check after API response
- VoiceContext.tsx:344 - Check before retry
- VoiceContext.tsx:359 - Check after retry response
Testing:
- Added Jest test configuration
- Added test suite with 5 race condition scenarios
- Added manual testing documentation
- Verified with TypeScript linting (no new errors)
