fix: 视觉自查修复9处 — 无头浏览器截图验证

通过playwright-core+系统Edge截图自查发现并修复:
1. glowTexture缺省size致createRadialGradient(NaN)全场景崩溃
2. 主光源在月背=月面纯剪影 → 改前左上(参考图光向)
3. 碎石死黑 → 冷补光fillCold
4. 裂缝像荧光管 → 减细减暗内嵌化
5. 月晕雾洗白纹理 → opacity 0.35→0.16
6. 撕裂太浅 → 深度2.8→3.4+撕裂缘更参差
7. 碎石贴月 → 拖带拉宽±48/向外3-18
8. 银河不可见 → skybox转向1.35/0.3
9. CTA文字被亮月面淹没 → 相机24→26.5+文字暗底

工具: 新增node静态服务器(替代僵死的python)+shoot.js截图工作流
