Align one-shot and streaming calls with the Claude Agent SDK shape while preserving Letta agent identity when supplied and creating hidden stateless workers otherwise.

Expose familiar query lifecycle controls and consume async prompts concurrently so callers can inject work while a turn is active. Keep model-selected queries stateless by requiring persistent-agent calls to use the agent configuration unchanged.

Allow model selection when querying an existing agent because the new conversation owns the override, and simplify the public documentation around query behavior.
