fix(tauri): fix MCP server spawn on Windows and PATH on macOS

Browse source 
- Windows: npm installs .cmd wrappers, not direct executables. Spawn
  via 'cmd /c openpencil-mcp-http' on Windows to resolve .cmd files.
- macOS/Linux: add fix-path-env-rs to inherit shell PATH in GUI apps.
- Add 'cmd' to shell spawn capabilities for Windows.

Fixes #226
