收口 MNote P0 P1 P2 审查尾项

- 归档 OnlyOffice live bridge、Page AI、mindmap、design governance 与相关 bug 条目
- 补齐 MinerU OCR 后端 runtime 合同与 smoke/test 基线
- 收口 ChatOnly/Doubao、ObjectIdentity、Page Aggregate compat 与 runtime owner 文档口径

验证：
- cargo test --manifest-path rust/Cargo.toml -p mnote-web local_ocr -- --test-threads=1
- cargo test --manifest-path rust/Cargo.toml -p mnote-web onlyoffice_bridge -- --test-threads=1
- git diff --check
- git diff --cached --check
- codegraph index . --force && codegraph status .
- codegraph sync . && codegraph status .

 - 页面 AI 编辑当前 local-first 主路径为：页面定位到真实 `.md` 文件，MNote 计算 `AiAccessScope` / allowed roots / selection，Hermes 或 Reasonix 在白名单目录内用自身 patch/diff/文件编辑能力写入，MNote 通过 watcher / refresh 同步 tiptap。`mnote.doc.markdown_edit` 只作为 cloud / remote agent / compat fallback；`mnote.block.*` 保留为结构性辅助（拖拽排序等）。两层操作模型已获 CLI Main（Lark Doc）参考实现验证。流式 apply + suggest/review（参考 BlockNote AI）作为 Phase C 设计冻结，当前不实施。
