feat: implement full UPDATE.md review — critical fixes, UI upgrade, infra hardening

Critical frontend bugs:
- Add TrackSubscribed/attach() for agent audio playback
- Fix decodeToString TypeError with TextDecoder
- XSS fix: innerHTML -> textContent in addMessage
- Fresh token on reconnect retry

Agent fixes:
- GemmaLLM subclass with reasoning_content fallback wrapper
- Disable Gemma 4 thinking mode via chat_template_kwargs (6.8s -> 0.5s)
- Remove duplicate session-level LLM
- Replace global _active_session with closure-based handler
- asyncio.create_task instead of deprecated get_event_loop
- Explicit silero VAD, topic filter on voice-control

Infra:
- supervisord: all programs log to /dev/stdout
- Dockerfile: uv sync --frozen with committed uv.lock
- nginx config moved to real file, token_server.py no longer served
- entrypoint.sh: cert persisted, only regenerated on IP change
- compose: healthcheck + cert volume
- token_server: CORS removed, room pinned to voice-room

UI upgrade:
- Orb UI with state machine (idle/connecting/listening/thinking/speaking)
- Streaming transcripts via lk.transcription text streams
- Barge-in hint, thinking chip, audio visualizer
- Glassmorphism, chat bubbles, settings sheet, light mode
- PWA manifest, favicon, wake-lock, safe-area insets
- localStorage conversation history
