Stream Conversation Turn
Reattach to the conversation's live turn and stream it via SSE.
Behind CHAT_DETACHED_TURNS_V1 a turn runs detached from the request that started it (see send_message). This endpoint replays the active turn's buffered frames from the start and then follows it live to the terminal frame, so a reloaded client resumes the trace instead of waiting blind.
Returns 204 when no turn is currently active for the conversation — the normal case, not an error.
Access is the READ check, not ownership: this replays a transcript that is already being written, and a channel conversation is readable by the whole tenant. Following "Open in anana" from Slack while the agent is still answering is the common case, and the ownership check turned exactly that into a 404 loop.

The active turn's SSE frames — replay, then live.
