fix: only mark serve-mode jobs complete on session.idle status

The monitor was treating every session.status SSE event as a completion
signal, causing jobs to be marked done seconds after launch. Now
session.status only triggers completion when status.type is 'idle',
matching the actual session lifecycle.
