Run an interactive or piped prompt session.

Resolves or creates a session, starts the ACP bridge, sends the prompt, and enters the event loop with signal handling and optional timeout. After the first prompt completes, becomes the queue owner — listening on a Unix socket for subsequent prompts from IPC clients until idle timeout.
