isBadgeOverlayNode matched role:'badge'|'pill'|'tag' and pulled those
children out of their parent's auto-layout, rendering them at (0,0) of
the parent and stacking them on top of siblings. But in this repo
badge/pill/tag are inline-component roles (see role-resolver NAME_EXACT_MAP
and strip-redundant-section-fills PROTECTED_ROLES) — they're meant to
flow in layout like any other child.
Rename to isOverlayNode and narrow to role:'overlay'. Add matching
"Layout-escape roles" guidance in role-definitions.md so generation
prompts can reach the new opt-in. Inline roles now flow correctly;
true floating decorations (notification dots, corner ribbons) still
have a dedicated marker.
