feat: 脚本创作+发布+市场体系

- 数据模型新增: title(必填), description(可选), status(draft/published)
- 新增 API: POST /scripts/:id/publish, GET /api/market (搜索+分页+runtime过滤)
- 前端首页重构: 选语言 → CodeMirror 编辑器(8种语言语法高亮) → 标题/描述 → 草稿/发布
- 新增 /market 页面: 浏览已发布脚本, 搜索+过滤+分页
- 详情页新增: 发布按钮(草稿→市场), title/description 展示
- Shell 类运行时显示 source 命令(继承环境变量)
- backend GetSourceCommand 支持 bash/zsh/sh/fish 四种 shell 格式
