- iconify: convert <circle>, <rect>, <ellipse>, <line>, <polygon>,
<polyline> to path d-strings. Fixes lucide:search (missing circle),
lucide:user (missing head), lucide:mail (missing envelope), etc.
- describe: show justify/items/sizing in layout description, detect
icon role, recurse issues into children at every depth level
- describe-issues: split layout checks into describe-layout-issues.ts
- New checks: fill without flex parent, absolute in flex, nested flex
without fill, duplicate sibling names, stroke color/weight mismatch,
circular frame without clip, excessive nesting, same fill as parent,
image placeholder without content, sibling height inconsistency,
text wrapping detection, alignment issues (between+HUG, between<2,
stretch with all fixed, equal children packed without gap)
- system-prompt: remove justify="evenly" — not supported
