Wassim SAMADandClaude Opus 4.7 bc0c73d449 Add SnapServices (grid + angle) to core (Phase 1, 3/6)

Pure math, no React, no scene access. Three primitives plus a facade:

- `snapScalar(value, step)` / `snapPointToGrid(point, step)` /
  `snapVec3ToGrid(point, step)` — regular grid snapping. Default
  step 0.25m matches the editor's wall tool.
- `snapPointToAngle(from, cursor, angleStep, gridStep?)` — locks a
  cursor to the nearest angle multiple from a fixed point, preserves
  distance, optionally re-grids the projected point. Default angle
  step π/12 (15°).
- `snapAngleToList(angle, list, tolerance)` — snaps a free angle to
  the nearest entry in a fixed list (e.g. 0/45/90/135) within a
  tolerance; returns the original angle otherwise. Handles wrap.
- `snapServices` facade — `grid.*` + `angle.*` namespaces. Stable
  contract that `DragAction.snap` callbacks receive. Phase 3 ports
  the existing `snapWallDraftPoint` family from
  `editor/.../wall-drafting.ts` under a `wall.*` namespace.

17 unit tests cover the math + the facade pass-through. No existing
callers re-wired yet — Phase 2 column/shelf tools are the first
consumers.

@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
