Add fn chat [agent-id] for interactive multi-turn chat with an agent from the CLI. Connects to a running fn dashboard / fn serve over its existing chat HTTP+SSE API and streams responses incrementally. Supports --session <id> to resume, --url / --token / --no-auth to target alternate servers, and stdin piping for scripted single-turn messages.
