What

The control-channel rename_session request now rejects a rename if the session_id it specifies doesn't match the current session. Separately, when a rename originates from a 'host' source, it's now also recorded and propagated through a new dedicated call, in addition to the existing rename mechanism.

Why

This prevents a session from being renamed by a mismatched request and adds proper tracking for renames initiated by the host application.
