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

+"""Small CLI to exercise connectors independently.
+
+python -m coworker.connectors.cli status
+    Show which platforms are configured (token present) + allowlist size.
+
+python -m coworker.connectors.cli fake [--user U1] [--allow U1]
+    Offline REPL: type messages as if they arrived from a platform; a built-in echo
+    handler replies through the gateway. Exercises auth + inbound dispatch + outbound
+    with no network. Try --user with someone NOT in --allow to see it dropped.
+
+python -m coworker.connectors.cli send --target telegram:12345 --text "hi"
+    Live outbound via the send_message tool (needs a bot token in the SecretStore).
