feat(knowledge): 项目名改 zncm + 去除元链接噪音 + 创建人显示人名

- project_name 默认 deerflow → zncm（config.yaml + 配置默认 + 模块内字面量）
- related_links() 返回空：笔记 Related 不再注入 index/_meta/taxonomy/hub 结构链接，
  只保留真实相关笔记的可点 [[标题]]；无相关笔记且无来源时不再渲染 ## Related 段
- 移除随之多余的项目 hub 页脚手架（index.md/_meta/taxonomy.md 仍由 obsidian 脚手架保留，可解析）
- GET /notes/{id} 用 auth provider 把 created_by/updated_by(UUID) 解析为邮箱
  (created_by_name/updated_by_name)，前端 footer 显示人名、解析不到才显示短 id
- 仅对新沉淀笔记生效，现有笔记不动
