feat(install): per-module agent merge and documentation overhaul

- Add per-module agent merge/unmerge for ~/.codeagent/models.json with
  __module__ tracking, user-customization protection, and agent restore
  on uninstall when shared by multiple modules
- Add post-install verification (wrapper version, PATH, backend CLIs)
- Install CLAUDE.md by default, best-effort (never crashes main flow)
- Fix 7-phase → 5-phase references across all docs
- Document 9 skills, 11 commands, claudekit module, OpenCode backend
- Add templates/models.json.example with all agent presets (do + omo)
- Fix empty parent directory cleanup on copy_file uninstall
- Update USER_GUIDE.md with 13 CLI flags and OpenCode backend
