- registry: getRoofAccessoryKinds() enumerates kinds declaring the
roofAccessory capability, in deterministic builtin-list order (mirrors
getSelectableKinds); exported from the registry barrel.
- apps/editor build-tab: a "Features" group under the Roof tile, discovered
from the registry (no DB) and activating each kind's roof-attach tool —
parity with the community editor's roof features.
- site-boundary-editor: hide the flag handle group around thumbnail captures
(they render on SCENE_LAYER so the thumbnail camera can't layer-filter them),
matching handle-arrow.tsx — keeps flags out of preset/snapshot thumbnails.
