fix(google): abort realtime sender on reconnect

[u9g]

Summary

• Add abortable Queue.get() support so blocked consumers can be cancelled without waiting for another item.
• Use abortable queue reads in Google realtime sender cleanup to avoid retaining stale send tasks across reconnects when no audio/input is flowing.
• Add a regression test for aborting a pending queue read.

Testing

• pnpm test -- agents/src/utils.test.ts
• pnpm --filter @livekit/agents build
• pnpm --filter @livekit/agents-plugin-silero build && pnpm --filter @livekit/agents-plugin-openai build && pnpm --filter @livekit/agents-plugin-google build
