Namespace history capabilities

Server-side history powers the recovery feature — see Real-time Data → Recovery & reliability for how to use it.

The 5-minute retention means messages are available for up to 5 minutes, but may become unavailable sooner if the namespace’s message limit is reached first — newer messages push out older ones once the cap is hit. Recovery only works for publications still present in the history window at the time of reconnect.
