feat: Tiptap替换为Vditor + MD存储重构 + Shortcode卡片扩展
- 编辑器:Tiptap 替换为 Vditor 3.11.2(wysiwyg 模式,本地托管 5.8MB,去 CDN) - 存储:Body 字段从 HTML 改为 Markdown,去除 BodyHTML,新增 Excerpt 列表摘要 - 安全:去除 bluemonday 依赖(MD 纯文本无 XSS 风险),go.mod 已清理 - Shortcode:新增 [zone:type:params] 扩展语法,支持活动/游戏/投票/资源卡片 - 图片上传:POST /api/posts/upload-image 直接返回 Vditor 原生响应格式 - 草稿:localStorage 键名改为 draft_post_body_md,与旧 HTML 草稿隔离 - 详情页:Vditor.method.min.js 客户端 MD → HTML 渲染,去 highlight.js CDN - 样式:去 Tiptap 样式 ~190 行,精简工具栏 CSS,新增卡片样式 - 文档:vditor-migration-plan.md 完整记录迁移决策、架构、用法
