feat: implement bootstrap conversion and installer updates (Phase 1-3)

Phase 1 - Bootstrap Scripts:
- Convert lib/ccs to 32-line bootstrap (was 1919 lines)
- Convert lib/ccs.ps1 to 39-line bootstrap (was 1826 lines)
- Delegate all functionality to Node.js via npx

Phase 2 - Help Text Updates:
- Add Requirements section to Node.js help (lines 172-175)
- Bootstrap scripts delegate --help to npx

Phase 3 - Installer Updates:
- Add Node.js 14+ detection with clear warning messages
- Remove deprecated shell deps (bootstrap handles all)
- Update completion messages with Requirements/First Run sections
- Update docs with new architecture

Total code reduction: 3745 → 71 lines (98.1%)

 - **Subsystem organization**: Clear separation (auth, delegation, glmt, management, utils)
 - **Naming conventions**: handler, executor, manager, validator, formatter, parser suffixes
 
+**v4.5.0 Installation Standards**:
+- **Bootstrap-based installers**: Native shell wrappers delegate to Node.js via npx
+- **Node.js requirement**: 14+ required (checked during install)
+- **No shell dependencies**: error-codes.sh, progress-indicator.sh, prompt.sh removed
+- **First-run bootstrap**: Auto-installs @kaitranntt/ccs npm package globally
+
 Following these standards helps maintain the quality, modularity, and extensibility of the v4.x architecture while enabling future development with AI delegation, shared data management, and comprehensive diagnostics.
