Merge agent-mode: v2 rewrite complete
- Removed all v1 code (-2800 lines) - Simplified state to just default_host + base_domain - Atomic port allocation via flock - --container-port flag for Docker - Custom domains shown in ship list - Caddyfiles preserved on redeploy - JSON output by default, --pretty for humans
