effect-uai agentic-loop

Long-lived chat agent. Drains a user-message queue between cleanly- finished turns; bursts of typing get coalesced into one batch via a debounce window; tool-call turns run straight through to the next iteration without checking for new user input.

Reach for this when the user says any of:

• "Long-lived chat agent with a queue / WebSocket"
• "Coalesce burst messages into one user turn"
• "Interactive CLI agent that keeps running"

The design move

The whole loop turns on one question at the top of each iteration:

Does the model need fresh user input, or does it still owe us a response?
