Add interview recovery and the architecture doc
main·
Commit

- Silence after a question: nudge at 12 s, move on at 25 s, counted from the end of the interviewer's voice
- Short phrases at the start of an answer: repeat, what do you mean, I don't know, pause, resume, stop, and garbled audio, all handled out loud
- Pause and Resume buttons; a hidden tab or lost microphone pauses
- Two Gemma failures in a row switch to written follow-ups, noted for the report
- docs/ARCHITECTURE.md: pieces, one answer end to end, lifetimes, review
