- Changed MAX_FRAGMENT_SIZE from 500 to 150 bytes to match iOS/Rust
- Fixed fragment ID generation to use 8 random bytes instead of string
- Implemented automatic fragmentation in BluetoothConnectionManager
- Added 20ms delay between fragments to match iOS/Rust implementation
- Updated fragment calculation to account for full packet overhead (34 bytes)
This ensures Android-generated fragments fit within iOS's default 185-byte BLE MTU,
fixing issues with commands like ?ls -la and ?ifconfig failing on iOS devices.
