- Power grid: /api/state/power (circuits, load, overload detection)
- Pipe contents: /api/state/pipes?type=gas|liquid (debug plumbing)
- CO2 tracking: /api/state/co2 (find CO2 pockets)
- Temp zones: /api/state/temperature/zones (hot/cold spots)
- Morale: /api/state/morale

- Skills: /api/state/duplicants/skills (attributes + skill trees)
- Assign job: /api/action/assign_job
New CLI commands: save, save_as, load, saves, power, pipes, co2,
temp_zones, morale, diseases, storage, skills, assign_job
CLI help reorganized with clear categories: Save/Load, Grid Analysis, Colony Management
