New browse meta-command: ux-audit extracts page structure (site ID, navigation,
headings, interactive elements, text blocks) as structured JSON for agent-side
UX behavioral analysis. Pure data extraction — the agent applies the 6 usability
tests and makes judgment calls. Element caps: 50 headings, 100 links, 200
interactive, 50 text blocks.
New snapshot flag: -H/--heatmap accepts a JSON color map mapping ref IDs to
colors (green/yellow/red/blue/orange/gray). Extends existing snapshot -a
annotation system with per-ref colors instead of hardcoded red. Color whitelist
validation prevents CSS injection. Composable — any skill can use it.
