feat: implement TS3 protocol layer, session management, and ServerQuery client

- Add real X25519 ECDH key exchange for initivexpand2 bootstrap
- Add P-256 identity key generation with TeamSpeak tomcrypt format
- Add session event loop with tokio::select! for packet/command handling
- Add ServerQuery TCP client with typed parsing (channels, clients, permissions)
- Add Tauri commands: connect (session-based), join_channel, send_message, disconnect
- Add frontend ServerQuery snapshot panel
- Fix CI: Node 22, rustup setup, npm install, workspace checks
- Add mock UDP handshake tests through initserver
- 54 tests passing across shared, tscore, tsaudio, tsdb
