feat(knowledge): 可跳转 wikilink + 真实相关 note + 一对话多页

- [[wikilink]] 解析器：note id / vault_path / 标题 / vault 元页 / missing
- 前端 MarkdownRenderer 把非数字 [[...]] 渲染成可点链接，元页弹窗查看，缺失置灰
- vault 脚手架补建项目 hub 页，三个结构性链接（index/taxonomy/hub）始终可跳
- capture 时按标题+摘要+区分性标签检索同主题 note，注入真实 [[标题]] 到 Related + 记 related 图谱边
- LLM 提取支持 notes[] 数组，一次对话拆 1~4 页并按标题互链（multi_note_enabled 开关）
- 新增接口 POST /resolve、GET /notes/{id}/wikilinks、GET /vault-page
- 新增配置 related_notes_enabled / related_notes_limit / multi_note_enabled
