feat: 电影级真实感重构 — 真实月面/银河/泛光/撕裂破碎

按用户参考图(破碎月亮)对齐的整套真实感升级:
- 月球: SSS/NASA 2K真实纹理+运行时亮度转凹凸, 顶点撕裂伤口(不规则锯齿轮廓)+发光裂缝(emissive放射纹+断面代码)+伤口辉光脉动
- 破碎: 2块大碎片(顶点扰动)+220块Instanced碎石量级谱(伤口切线拖带,各自漂移翻滚)+5团青灰尘埃云(烟尘流动)
- 太空: 真实星野天球(SSS银河2K)替换程序点星, 保留近景尘埃视差层
- 太阳: 亮度>1的小烈核心(推过泛光阈值)+克制光晕+变形宽银幕横向光纹
- 渲染: ACES电影色调映射+UnrealBloomPass泛光(three.module+8个后处理文件本地化,importmap加载)
- 移动端降级: 关泛光+减粒子
- 页脚: NASA/SSS纹理CC-BY署名
