feat: doors and windows on roof-segment wall faces
Openings now host on the walls a roof segment generates — the base walls under the roof and the coplanar gable/shed/gambrel end faces, so a window can sit in a gable pediment. - core: roof-segment-walls.ts models the four vertical faces as 2D frames (u along face, v height) with convex profile polygons that mirror the wall volume getRoofSegmentBrushes builds; rect-in-profile clamping and anchored resize limits via half-plane algebra. - schemas: optional roofSegmentId on door/window; position is the segment-local wall mid-plane center, rotation[1] the face yaw. - cut: reuses capabilities.roofAccessory.buildCut; new cutScope: 'wall' subtracts from the wall brush only. cascadesViaHostSegment keeps the roof-merge loop from consuming door/window dirty marks (their own systems cascade via parentId). - tools: roof:* handlers in door/window tool + move-tool (the Build-tab preset path), with roofSegmentId cleared/restored across every roof<->wall re-anchor and revert; shared hit resolver normalizes normals through world space (merged mesh vs painted segment frames). - fix: RoofSystem no longer rebuilds per-segment CSG in accessory-reveal mode — the uncut rebuild used to draw over the merged shell's fresh opening until deselect. - fix: the walkthrough collider world now prunes by renderer-effective visibility; stale uncut segment CSG inside the hidden segments-wrapper blocked the player at openings the merged shell had cut through. Known gap: painted segments render per-segment CSG without accessory cuts (pre-existing, also affects skylight/dormer).
