Reorganize project structure

- Move documentation to organized docs/ directory structure
- Add CLAUDE.md for AI-assisted development guidance
- Create comprehensive 5-phase roadmap for indoor positioning system
- Move AT command manual and hardware images to docs/
- Update README with hardware links and project overview
- Remove sleep mode and OTA functionality for simplification
- Clean up project structure for production development
