contract: add host + Health URL columns, use health_url param

- Added Host column (Abiba: 192.168.68.24, Hermes agents: 192.168.68.123)
- Changed Health Port → Health URL with full http://host:port/health URLs
- Updated Check 1 to reference {{health_url}} instead of {{health_port}}
- Added .gitignore for .agents/ (OpenProse run state)
