v0.2.0

What's new

• Streaming gateway playback — serve-mode TTS now pipes audio/mpeg chunks directly from tts-gateway to mpv/ffplay, replacing temp-file-per-sentence synthesis.
• Canonical gateway API — new gateway-client module with speakSync (/v1/speech) and speakStream (/tts/stream), matching the reference tts-gateway contract.

Fixes

• Stream session cleanup crash — releaseLock() on Bun delayed fetch response bodies no longer throws TypeError during playback completion.
• Payload encoding mismatch — /v1/speech now correctly sends multipart/form-data and /tts/stream sends application/json, matching the gateway's FastAPI route signatures.

Misc

• Tightened local quality checks (prettier, typecheck)
• Updated docs for streaming TTS setup and /v1/speech references
