feat: v0.10.0 quieter Matrix, worktrees, usage pace, repo diffs, copy reply, turn timer, compact

- Matrix "needs you": ignore Claude's idle reminder (no red, no post); post
  only when no tab is in view, after 60 s, once per session per 10 min, and
  say what is asked. Closes #50
- devdesk new NAME PROJECT --worktree: own checkout on devdesk/NAME,
  cleaned up on end when clean/merged. Closes #44
- Usage meters: reset time, pace warning; Matrix ping past 90% when away.
  Closes #45
- Repo panel lists changed files; click opens the diff. Closes #46
- Copy Claude's last reply (--last-reply). Closes #47
- Turn timer in chip, title and cards. Closes #48
- Compact button at 80% context when idle. Closes #49
