A city is a directory containing city.toml and .gc/ runtime state.
Initialization
gc init # Initialize city in current directory
gc init <path> # Initialize city at path
Starting and stopping
gc start # Start city under the supervisor
gc start <path> # Start city at path under the supervisor
gc supervisor run # Run the supervisor in the foreground
gc start --dry-run # Preview what would start
gc stop # Stop the current city
gc restart # Stop then start
gc init and gc start register the city with the machine supervisor,
ensure it is running, and trigger an immediate reconcile. Interactive
sessions are created separately with gc session new <template>.
