feat(cli): implement TLS/WSS support for WebSocket connections
Add TLS transport abstraction for secure WebSocket connections: - Create tls.zig module with TlsStream struct for TLS-encrypted sockets - Implement Transport union in client.zig supporting both TCP and TLS - Update frame.zig and handshake.zig to use Transport abstraction - Add TLS handshake, read, write, flush, and close operations - Support TLS 1.2/1.3 protocol versions with error handling - Zig 0.15 compatible ArrayList API usage Enables wss:// protocol support for encrypted server communication.
