Reorganize project structure and create development roadmap

- Move documentation to organized docs/ directory structure
- Add dev notes
- 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

+## AT Command Support
+
+Complete implementation of all AT commands from the official manual:
+
+### Basic Commands
+- `AT?` - Test connection
+- `AT+GETVER?` - Get firmware version
+- `AT+RESTART` - Restart module
+- `AT+RESTORE` - Factory reset
+- `AT+SAVE` - Save configuration
+
+### Configuration
+- `AT+SETCFG` / `AT+GETCFG?` - Device configuration
+- `AT+SETANT` / `AT+GETANT?` - Antenna delay calibration
+- `AT+SETCAP` / `AT+GETCAP?` - System capacity settings
+- `AT+SETRPT` / `AT+GETRPT?` - Auto-reporting control
+
+### Network & Power
+- `AT+SETPAN` / `AT+GETPAN?` - Network ID configuration
+- `AT+SETPOW` / `AT+GETPOW?` - Transmission power control
+- `AT+SLEEP` - Sleep mode for battery conservation
+
+### Data Communication
+- `AT+DATA` / `AT+RDATA` - Custom data transmission
+- Real-time range reporting via `AT+RANGE` parsing
+
+## Library Features
+
+The enhanced UWBHelper library provides:
+- **Complete AT command coverage**
+- **Advanced range data parsing** for multiple anchors
+- **Position calculation algorithms** (trilateration, multilateration)
+- **Anchor position management** for auto-positioning
+- **Distance filtering** for improved accuracy
+- **Backward compatibility** with existing code
+
