Feedback Integration

Passively approving is fine, but editing is better. If the agent generates a draft email, the human might want to change the tone.

1. Agent: Generates Draft 1.
2. Interrupt: Wait for Human.
3. Human: "Make it friendlier." (Updates State).
4. Resume:
5. Router: Sees human feedback -> Routes back to DraftNode.
6. Agent: Generates Draft 2.

This collaborative loop creates higher quality output than fully autonomous generation.
