List the conversation

Returns the Session's conversation in order: the opening prompt, each message in it afterwards, and one reply for every finished turn. kind tells them apart. A reply's content is the turn's result_summary (empty when the turn left none), with the turn's status and outcome beside it, so a failed or cancelled turn is listed and marked as such; a structured result the agent declared is result on getSession, and a turn's intermediate text and tool activity are events (listSessionEvents). A reply is listed once every turn before it has finished. Delivery notes are not included. Cursor-paginated: pass end_cursor as after, and keep polling with it to receive what is said next. An item's cursor belongs to this list only and is not a message seq.
