feat: 实现内容系统 MVC(Post CRUD + 审核流转)
按 content-system.md 设计文档,实现帖子内容系统的最小可行 MVC。 新增: - Model: Post 模型,含 5 种状态(draft/pending/approved/rejected/locked) - Repository: post_repo.go,分页查询(前台 approved 列表 + 后台全状态筛选) - Service: post_service.go,核心业务逻辑(状态流转、Markdown 渲染 Goldmark) - Controller: post_controller + admin_post_controller,SSR 页面 6 个 + API 13 个 - Template: 列表/详情/编辑器/404 + 管理员列表,各配 CSS/JS - 路由: /posts, /posts/:id, /posts/new, /posts/:id/edit, REST API, Admin API - gomod: + github.com/yuin/goldmark v1.8.2 修改: - Main: AutoMigrate Post 表 - Router: deps 注册 PostService/Controller,路由注册 - Nav: 新增“帖子”导航链接 - Admin Sidebar: 新增“内容管理”入口 设计: - 审核开关复用 audit.enabled,开启时帖子为 draft,关闭后直接 approved - 仅 approved 公开可见,作者/admin 可预览非公开状态帖子 - 严格分层 ISP 接口: Controller → postUseCase, Service → postStore, Repo → *PostRepo - 状态保护: pending/locked 禁止编辑,rejected 编辑后自动重置为 draft
