* Add catalog-based material presets across structural nodes
* Fix material picker fallback and wall visible highlights
* Preserve wall materials in selection highlights
- Add MaterialSchema with 10 presets (white, brick, concrete, wood, glass, metal, plaster, tile, marble, custom)
- Add material field to Wall, Slab, Door, Window, Ceiling, Roof, RoofSegment nodes
- Create MaterialPicker UI component with preset selection and custom properties
- Update all renderers to support material rendering with caching
- Add Material section to all node panels (WallPanel, SlabPanel, DoorPanel, WindowPanel, CeilingPanel, RoofPanel, RoofSegmentPanel)
- Update AGENTS.md with Material System documentation
Key Additions & Changes:
Interactive Length Control: Replaced the static "Length" text with an editable SliderControl component.
Vector Math Implementation: Added handleUpdateLength, a function that recalculates the wall's end position ($P_{end}$) based on the user's input while preserving the wall's original direction.
Real-time Geometry Updates: Integrated the change with useScene and dirtyNodes to ensure the 3D mesh updates instantly in the viewer as the slider moves.
UX Consistency: Used the existing SliderControl and PanelSection patterns to match the Pascal Editor's design system.
