feat: OpenMesh 基础平台与 MD/PDF 转换技能

- 后端: coworker 智能体框架, WS API, 文件上传, 附件处理
- 前端: Open WebUI, 文件全量走 upload API (含 MD/TXT/JSON 等文本类)
- 技能: md-to-office (pandoc + wkhtmltopdf)
- 修复: 上传文件路径丢失, Agent 搜索浪费, 输出文件跑到 uploads/
- 打包: PyInstaller one-dir, 预打包 pandoc/wkhtmltopdf/chromium

+"""Phase 1 gate — built-in personas resolve to the same toolsets as the legacy agents.

+The equivalence net: routing Code/Cowork through the persona registry must yield the exact
+same tools the agent builders produce, and Ops (a markdown persona) must compose the knowledge
+toolset. Ties back to the Phase 0 catalog equivalence."""
