Developer d0cdeb2ac4 fix(viewer): 修复墙体材质切换后缩放旋转时颜色恢复问题

问题描述：
选中墙体并切换材质颜色后，在界面上进行缩放、旋转或移动操作时，
墙体实际渲染的颜色会恢复为原来的白色，但颜色选项卡显示仍为选中的颜色。

根本原因：
WallCutout 系统在每次相机移动时，直接使用固定的白色材质覆盖墙体材质，
完全忽略了用户在节点上设置的自定义材质。

修复内容：
- 为每个墙体创建独立的材质对象，支持用户自定义颜色
- 支持预设颜色（brick, concrete, wood 等）和自定义颜色属性
- 添加材质哈希值跟踪，检测材质变化并重新创建材质
- 提取 getWallHideState() 辅助函数，优化代码结构
- 添加预设颜色映射的类型安全改进，使用 as const 和 keyof 类型操作

README.md

@pascal-app/viewer

3D viewer component for Pascal building editor.

Installation

npm install @pascal-app/viewer @pascal-app/core

Peer Dependencies

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

What's Included

Viewer Component - WebGPU-powered 3D viewer with camera controls
Node Renderers - React Three Fiber components for all node types
Post-Processing - SSGI (ambient occlusion + global illumination), TRAA (anti-aliasing), outline effects
Level System - Level visibility and positioning (stacked/exploded/solo modes)
Wall Cutout System - Dynamic wall hiding based on camera position
Asset URL Helpers - CDN URL resolution for models and textures

Usage

import { Viewer, useViewer } from '@pascal-app/viewer'
import { useScene } from '@pascal-app/core'

function App() {
  return (
    <div style={{ width: '100vw', height: '100vh' }}>
      <Viewer />
    </div>
  )
}

Custom Camera Controls

import { Viewer } from '@pascal-app/viewer'
import { CameraControls } from '@react-three/drei'

function App() {
  return (
    <Viewer selectionManager="custom">
      <CameraControls />
    </Viewer>
  )
}

Viewer State

import { useViewer } from '@pascal-app/viewer'

function ViewerControls() {
  const levelMode = useViewer(s => s.levelMode)
  const setLevelMode = useViewer(s => s.setLevelMode)
  const wallMode = useViewer(s => s.wallMode)
  const setWallMode = useViewer(s => s.setWallMode)

  return (
    <div>
      <button onClick={() => setLevelMode('stacked')}>Stacked</button>
      <button onClick={() => setLevelMode('exploded')}>Exploded</button>
      <button onClick={() => setWallMode('cutaway')}>Cutaway</button>
      <button onClick={() => setWallMode('up')}>Full Height</button>
    </div>
  )
}

Asset CDN Helpers

import { resolveCdnUrl, ASSETS_CDN_URL } from '@pascal-app/viewer'

// Resolves relative paths to CDN URLs
const url = resolveCdnUrl('/items/chair/model.glb')
// → 'https://pascal-cdn.wawasensei.dev/items/chair/model.glb'

// Handles external URLs and asset:// protocol
const externalUrl = resolveCdnUrl('https://example.com/model.glb')
// → 'https://example.com/model.glb' (unchanged)

Features

WebGPU Rendering - Hardware-accelerated rendering via Three.js WebGPU
Post-Processing - SSGI for realistic lighting, outline effects for selection
Level Modes - Stacked, exploded, or solo level display
Wall Cutaway - Automatic wall hiding for interior views
Camera Modes - Perspective and orthographic projection
Scan/Guide Support - 3D scans and 2D guide images
