Carry conversations into new sessions with a visible summary
- Bots get continue_in_new_session: the bot writes a title and summary, the session closes for good (read-only) and the new one opens with the summary as a "Carried over from the last session" message that links back to the old session. - Continue in new session (conversation menu, sessions modal) and the automatic rollover at the session length do the same; New session now starts a fresh, unlinked session. - Session length is an app setting in Settings > General. - ?session_id= opens a session; a carried-over one shows a bar linking to where the conversation went on instead of the composer. - The thread can open the previous session above the current one (shown only, never in the prompt), and replies get search_past_sessions and read_past_session. - Sessions are named from their opening messages, not their latest, and a carried summary is labelled as the earlier session's.
