Complete breakdown of all 104+ directories and their purposes:
- Root level directories with explanations
- Detailed structure for each major subsystem:
  * config/ - Configuration files
  * dbal/ - Database abstraction (Phase 2 & 3)
  * deployment/ - Deployment scripts
  * docs/ - Documentation hub
  * e2e/ - Playwright tests
  * fakemui/ - 151+ Material Design components
  * frontends/ - Next.js web app
  * packages/ - 51 application packages (12 core, 39 optional)
  * schemas/ - YAML and JSON schemas
  * services/ - Daemon services
- 51 packages with entity-type folder structure
- Key files at root level
