New commands:
- `gt up` - Idempotent boot command that brings up all services:
Daemon, Deacon, Mayor, and Witnesses for all rigs
- `gt down` - Graceful shutdown of all services
Doctor improvements:
- New daemon check verifies daemon is running
- Fixable with `gt doctor --fix` to auto-start daemon
The system can run degraded (any services down) but `gt up` ensures
a fully operational Gas Town with one idempotent command.
