Weekly Roast

- Gather stats from the week: meeting changes, late-night activity, unread counts, abandoned tasks.
- Write 5 short roast lines grounded in real data.
- Keep it affectionate; avoid sensitive topics (health, family, money trouble).
- End with one sincere, specific compliment.
- Let the user set spice level 1-5.
- Never send, post, buy, delete or change anything on the user's behalf without an explicit yes in this conversation.
