Add bootstrap installer with UPX optimization

New lightweight installation method for Raspberry Pi:
- bootstrap.sh: Smart installer downloads UPX-compressed binary (1.6MB)
- Falls back to full package if GitHub release unavailable
- Auto-installs dependencies (tor, curl, upx-ucl)
- Generates secure config with random RPC password
- Enables Tor service automatically

Benefits vs full package:
- 68% smaller download (1.6MB vs 5.1MB)
- Faster setup on slow Pi connections
- Same final result as full install

Main package still uses uncompressed 5.1MB binary.
Bootstrap uses UPX version for initial download only.
