When a session enters context compaction, the gateway previously had no signal — users saw the agent freeze for tens of seconds with no explanation.

Adds a single _emit_status call before compression starts so platforms can surface 'Compacting context...' before the operation begins. Regression test included.

Salvage of #25394 by @raymaylee.
