PDF Scheme Editor progress widget

This artifact is served by the SHD MCP backend as ui://shd/pdf-scheme-editor-progress/v1.html.

The HTML is standalone, uses the MCP Apps bridge first, and keeps window.openai as a compatibility extension. It has no external script or network dependency. The widget provides a read-only scheme document progress dashboard.
