fix(theme): 补抠封闭白区（光环/车架/轮圈内），人物与单车加渐隐遮罩

Browse Source

问题（用户发现）：
1. 光环环内是白块 —— 此前只用「边界洪泛」抠底，被图形围起来的封闭白色
   区域（光环内圈、单车车架三角、轮圈内扇形）与边界不连通，没被处理
2. 人物与单车直接贴在页面上显得突兀

修复：
- 对三张图再补一次「封闭白色区域」清理（按面积阈值）：
  人物抠 3675px（含光环 2665）、单车抠 19657px、图标抠 308px；并同步重生成 favicon
  已验证脸部 / 袜子 / 衣服等服装白未被误抠（保留 34px 噪点级）
- 立绘 opacity .92 + 上下渐隐遮罩；单车 opacity .8 + 两端渐隐 + saturate(.92)

验证：四套脚本 81 项全通过；1440 宽 0 横向溢出；局部放大确认光环内圈可透出背景
