Blaze Livekit plugin integration

[HoangPN711]

Summary

Add @livekit/agents-plugin-blaze, a new Blaze provider plugin for agents-js with support for:

• STT
• TTS
• LLM

The implementation is scoped under plugins/blaze and follows the existing provider/plugin structure used by other integrations in this repo.

What changed

• added a new plugins/blaze package with build/package wiring
• implemented Blaze STT integration
• implemented Blaze TTS integration
• implemented Blaze LLM integration
• added Blaze config/model helpers and public exports
• added package README
• added unit tests for config, STT, TTS, and LLM
• added changeset + workspace plumbing updates required for package release/build

Notes

• the change is isolated to the Blaze plugin package, aside from workspace/release wiring
• Blaze STT is batch-only in this plugin; streaming STT is intentionally unsupported
• follow-up commits addressed review feedback around retry/error handling, TTS/WebSocket lifecycle handling, batching behavior, and stream edge cases

Changeset

• patch bump for @livekit/agents-plugin-blaze

Test plan

• pnpm vitest run plugins/blaze/src/*.test.ts
• pnpm --filter @livekit/agents-plugin-blaze build
• pnpm --filter @livekit/agents-plugin-blaze lint

Have you ran the tests on those plugins?

Have you ran the tests on those plugins?

Yes — I re-ran the plugin tests and checks after the latest fixes.

What I validated:

• Unit tests for the Blaze plugin (LLM/STT/TTS)
• Type checking
• Lint/format checks

I also added a regression test for the stream options race-condition and fixed the STT/TTS typed-array buffer window handling from review feedback.

@toubatbrian
I addressed the Devin Review findings and re-ran the Blaze plugin tests after the latest fixes.

Validation:

• pnpm vitest run plugins/blaze/src/*.test.ts → 56/56 passing

Devin Review is clean now. Please take another look when you have a chance.

🟡 TTS updateOptions type accepts sampleRate but silently ignores it

The updateOptions method's type signature is Partial<Omit<TTSOptions, 'config'>>, which includes sampleRate. However, the implementation handles every other field from TTSOptions (language, speakerId, authToken, model, audioFormat, audioSpeed, audioQuality, timeout, normalizationRules, batchMinChars, batchTargetChars, batchMaxChars, batchMaxWaitMs, interSentenceSilenceMs, apiUrl) except sampleRate. A caller invoking tts.updateOptions({ sampleRate: 48000 }) would have the change silently dropped — this.#opts.sampleRate remains at the old value, and the base class TTS.sampleRate getter (backed by a private field set in the constructor at plugins/blaze/src/tts.ts:925) also remains unchanged. The type should exclude sampleRate to prevent the misleading contract.

Suggested change

	updateOptions(opts: Partial<Omit<TTSOptions, 'config'>>): void {
	updateOptions(opts: Partial<Omit<TTSOptions, 'config' | 'sampleRate'>>): void {
