provideFakeAgent

Registers an in-process FakeAgent under AGENT.

Use for offline demos and development. Drop-in replacement for provideAgent({ url }) when no real backend is available.

Pass script to stream exact AG-UI events instead of the canned token reply — the adapter reduces them into toolCalls(), state(), customEvents(), and interrupt() exactly as it would real wire events, and emits each one on rawEvents$.
