X reply engine with per-account caps

Steps

1. A LeadScout sweep searches X twice a day (7:30a and 5:30p CT) and adds scored rows (1-5) to queue.csv.
2. Each account has a role: the personal account gives "I've been there" replies to high-score leads; the brand account answers how-to and product questions.
3. Caps live in one file, caps.json: personal 6/hour and 50/day, brand 3/hour and 20/day, at most 3 replies per run, 2 per author per day, and a 4-minute gap between replies.
4. check_cap.py @account runs before every reply and prints how many are allowed right now (exit 1 if none).
5. Link rule: at most 1 in 3 replies carries a link, and only when it answers the question.
6. Every evening a tracker row records: posted?, reply URL, replies back, clicks, sales.
