fix(voice): prevent recorder interruption deadlock

[toubatbrian]

Summary

• delegate recorder playout waits to the wrapped audio output so synchronized outputs can reconcile dropped interrupted segments
• add a regression test covering downstream wait delegation
• add a patch changeset for @livekit/agents

Test plan

• Reproduced the pre-fix deadlock with chained Cue turns using Deepgram Nova-3, GPT-5.4, and Inworld TTS
• Verified the same Cue scenario resolves after the fix
• pnpm exec vitest run agents/src/voice/recorder_io/recorder_io.test.ts --exclude '.worktrees/**'
• pnpm format:check
• pnpm lint
• pnpm typecheck
• pnpm build
