baseline: dsh 工作区基线快照（2026-09-10，全新历史起点）

本提交为 dsh_mcn_workshop 仓库的首个提交（旧仓 dsh_MCNProject 已停用），
完整固化 C:/Users/Administrator/.dsh 当前磁盘状态。

1) 临时数据清理：移出 sessions/(81M)、logs/、skill-backup-20260906/(14M)、
   scripts/__pycache__、storages/workspace.json.bak —— 合计 94M（.dsh 162M → 68M）
2) 凭据脱敏：.credentials.yaml（含明文 DEEPSEEK_API_KEY）移出 git 跟踪并加入
   .gitignore；mcn-data-insight/scripts/setup_redfox_key.py 中真实 key 示例改为占位符
3) .gitignore 增补 logs/、skill-backup-*/ 规则
4) 技能结构以当前磁盘状态为准：skills/ = mcn-short-video / impeccable / taste-skill /
   dsh-multi-user-migration；旧技能目录（mcn-dou-analysis、storyboard-prompt、
   short-video-script、browser-harness、mcn-data-insight）与
   profiles/web/node_modules/dsh-vision-router 本地已不存在，本提交记为删除
