ChatCreateRequest
Start one outbound chat with a named Chat Agent, mirroring POST /v1/calls. The agent sends the first text, composed from its instructions and these inputs, and then answers each inbound text.
At most one open chat is allowed per (to_phone_number, from_phone_number) pair, so an inbound reply always points to exactly one run; a second start to a busy pair is refused.
