Runs a Friday weekly review — wins, unfinished carryover, metrics check-in, next week's top 3 — and appends it to a running weekly-reviews.md log. Use when the user says "run my weekly review", "weekly review", "wrap up my week", "what did I ship this week", or wants a scheduled end-of-week reflection. Don't use for the daily morning kickoff (use morning-brief) or extracting actions from one meeting (use meeting-notes-actions).
