- Add mintelTldr renderer for summary boxes
- Fix iconList to display item.title instead of empty item.description
- Rewire all 6 diagram block types to render via Mermaid
- Remove ai property from 30 non-essential blocks (46 -> 13)
- Tighten MemeCard to 5 verified templates, max 1 per article
- Fix PerformanceChartBlock syntax after ai removal
