Add unit tests for StreamingQueue utility class

[kanweiwei]

The StreamingQueue class (web/src/utils/streaming-queue.ts, 92 lines) has no tests.

It's a self-contained class with add(), flushNow(), and destroy() methods that batches streaming text updates using requestAnimationFrame.

What to do:

1. Read web/src/utils/streaming-queue.ts to understand the API
2. Create web/src/utils/__tests__/streaming-queue.test.ts
3. Test cases to cover:
   • add() queues items and flushNow() delivers them
   • destroy() stops further processing
   • Empty queue behavior
   • Multiple adds before flush
4. Mock requestAnimationFrame in tests (or just test via flushNow())
5. Run: pnpm -C web run test -- --run streaming-queue

Skills needed: TypeScript, Vitest

Estimated time: 1 hour

The StreamingQueue class needs unit tests for its batching logic and lifecycle. I'd handle this by writing Vitest tests with mocked requestAnimationFrame to verify add(), flushNow(), and destroy() behavior. Can have a PR up within an hour—I regularly test similar utility classes in TypeScript/Next.js projects.

The StreamingQueue class needs unit tests for its batching logic using requestAnimationFrame. I'd handle this by creating a Vitest suite with mocked timers to test add(), flushNow(), and destroy() behavior in isolation. I can have a PR with comprehensive tests up within an hour, as I frequently write production tests for similar utility classes in TypeScript.
