## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
Add a "miC" toggle button to the MI agent that enables a full voice conversation loop: speak → transcribe → auto-submit to MI → speak response aloud → listen again.
## Implementation
- `lib/mi-voice-bridge.ts`: MiVoiceBridge class — Edge TTS via `claude-voice.jeffemmett.com` WebSocket + Web Speech Synthesis fallback
- `shared/components/rstack-mi.ts`: Voice mode state machine (IDLE → LISTENING → THINKING → SPEAKING → LISTENING), miC buttons in bar + panel header, voice status strip with waveform animation, auto-submit on 1.5s silence, TTS truncation (strips markdown/code, limits to ~4 sentences), echo prevention, interruption support
## Key Decisions
- Separate SpeechDictation instance from bar dictation (browser only allows one SpeechRecognition)
- No server changes — uses existing #ask() flow and parseMiActions()
- Edge TTS primary, browser speechSynthesis fallback
