Implements CLI for convoy management in Gas Town:
- gt convoy create <name> [issues...] - Creates convoy in town beads (hq-* prefix)
- gt convoy status [id] - Shows convoy progress and tracked issues
- gt convoy list - Lists all convoys with optional status filter
Convoys track issues across rigs using the 'tracks' relation type
and auto-close when all tracked issues complete.
