Quick status brief so the user can pick up where things left off — what changed, what state it's in, what's next.
Trigger when the user says "catch up", "catch me up", "where were we", "what's the status", "what's going on", or returns to a task/repo after a gap and wants an overview.
Output: since last time / current state / next step. Max 12 lines. Grounded in actual git status/log/diff, not guesses.
