Improve monopam sync and doctor commands
- Add git fetch --all to sync: fetches all remotes (including verse
remotes) instead of just origin
- Add Git.fetch_all and Git.log_range functions
- Rewrite doctor command to be more useful:
- Analyzes all remotes in each src/ directory
- Collects commits from remotes where we're behind
- Builds comprehensive status summary for Claude prompt
- Sends single prompt to Claude for holistic analysis
- Returns actionable recommendations
