refactor(skill): 主技能 subskill 目录更名 subskills（09-02 用户要求）

- V1.0/subskill/ → V1.0/subskills/（browser-harness/mcn-dou-analysis/mcn-script-review/mcn-video-prompt，git 识别 R100 纯重命名保留历史）
- 路径说明同步：V1.0/SKILL.md（96/105行）、Lite1.0/SKILL.md（66行）、mcn-dou-analysis/SKILL.md 红线行、操作规范.md 159/175行、mcn-work-shop app.js SKILL_HINT_ACCOUNT
- 用户环境 ~/.workbuddy/skills/短视频脚本创作/ 与源仓库 V1.0 同 inode（junction），自动同步无需单独改
- mcn-dou-analysis 内部 subskills/nuwa-skill-main 为正常结构不受影响
