Merge OrbitOS into project — one install, everything ready

- Added 15 OrbitOS skills (bundled in skills/orbitos/)
- Added vault structure templates (views, templates, prompts)
- Added install.sh (macOS + Linux)
- Removed references/orbitos-skills.md (no longer needed)
- Updated README: 30 skills total, unified install flow

Total: 9 mm* + 6 dependencies + 15 orbitos = 30 skills
