Convert JSON protocol to efficient binary format

Browse Source 
- Implemented compact binary encoding for packets and messages
- Reduced packet size significantly (13-byte fixed header + variable payload)
- Optimized for BLE's limited MTU with smaller message sizes
- Added BinaryProtocol.swift with encode/decode functions
- Updated all message types to use binary serialization
- Maintains all existing functionality with better performance
