feat: complete voice pipeline — fix wake word crash, bridge timeout, HA conversation agent

- Fix Wyoming satellite crash on wake word: convert macOS .aiff chimes to .wav
  (Python wave module only reads RIFF format, not AIFF)
- Fix OpenClaw HTTP bridge: increase subprocess timeout 30s → 120s, add SO_REUSEADDR
- Fix HA conversation component: use HTTP agent (not CLI) since HA runs in Docker
  on a different machine; update default host to Mac Mini IP, timeout to 120s
- Rewrite character manager as Vite+React app with schema validation
- Add Wyoming satellite wake word command, ElevenLabs TTS server, wakeword monitor
- Add Phase 5 development plan
- Update TODO.md: mark voice pipeline and agent tasks complete
