Wassim SAMADandClaude Fable 5 7afb286e47 feat(paint-slots): authored item materials + unified slot painting

Phase 1 + paint unification of the paint-slots plan.

- core: scene-material data layer (materials map mirroring collections,
  undo/partialize/setScene full-graph support), SceneMaterial schema,
  scene:/library: MaterialRef helpers + parseMaterialRef, slot id helpers
  (deriveSlotId/slotLabelFromId), slots map on ItemNode, hitObject on
  PaintResolveArgs, optional PaintCapability.commit.
- viewer: resolveMaterialRef (library:/scene: -> three material, null on
  dangling).
- nodes(item): renderer keeps authored GLB materials for slot-authored
  assets and applies per-slot overrides per-instance (never mutates the
  shared cached GLB); textures-off still collapses to furnishing role;
  non-authored items unchanged. Item paint capability + registration.
- editor: item joins the unified (nodeId, slotId) paint dispatch; item
  paint target + slot reset.

@pascal-app/core

Core library for Pascal 3D building editor.

Installation

npm install @pascal-app/core

Peer Dependencies

npm install react three @react-three/fiber @react-three/drei

What's Included

Node Schemas - Zod schemas for all building primitives (walls, slabs, items, etc.)
Scene State - Zustand store with IndexedDB persistence and undo/redo
Systems - Geometry generation for walls, floors, ceilings, roofs
Scene Registry - Fast lookup from node IDs to Three.js objects
Spatial Grid - Collision detection and placement validation
Event Bus - Typed event emitter for inter-component communication
Asset Storage - IndexedDB-based file storage for user-uploaded assets

Usage

import { useScene, WallNode, ItemNode } from '@pascal-app/core'

// Create a wall
const wall = WallNode.parse({
  points: [[0, 0], [5, 0]],
  height: 3,
  thickness: 0.2,
})

useScene.getState().createNode(wall, parentLevelId)

// Subscribe to scene changes
function MyComponent() {
  const nodes = useScene((state) => state.nodes)
  const walls = Object.values(nodes).filter(n => n.type === 'wall')

  return <div>Total walls: {walls.length}</div>
}

Node Types

SiteNode - Root container
BuildingNode - Building within a site
LevelNode - Floor level
WallNode - Vertical wall with optional openings
SlabNode - Floor slab
CeilingNode - Ceiling surface
RoofNode - Roof geometry
ZoneNode - Spatial zone/room
ItemNode - Furniture, fixtures, appliances
ScanNode - 3D scan reference
GuideNode - 2D guide image reference

Systems

Systems process dirty nodes each frame to update geometry:

WallSystem - Wall geometry with mitering and CSG cutouts
SlabSystem - Floor polygon generation
CeilingSystem - Ceiling geometry
RoofSystem - Roof generation
ItemSystem - Item positioning on walls/ceilings/floors
