Add ops-status-packet.py (reusable generator) and ops-status-template.md.
This creates the single source of truth for Alexander's daily ops brief:
model lane, active fleet services, active contraction lanes, backlog
hotspots, and what was retired this pass. Replaces scattered status
fragments — one packet to rule them all.
Also fix stale VISION_MODEL reference in glitch-detection.md (gpt-4o
→ qwen3:30b) to keep model naming consistent across docs.
Closes#882
