Editor.commands type doesn't include some superdoc extension commands (createDocumentSection, updateSectionById, etc.)

[Clstialdev]

Package: superdoc + @superdoc-dev/react

Problem

editor.commands.updateSectionById(), createDocumentSection(), and other extension commands work at runtime but aren't on the public Editor type. TypeScript reports "Cannot invoke an object which is possibly 'undefined'" because the exported EditorCommands uses an index signature that makes every command | undefined, and doesn't list the extension commands.

Here is the line that is used to infer the type of any 'other' command including these ones:
in superdoc-editor/src/index.d.ts

  // Allow any other command (for extension commands)
  [commandName: string]: ((...args: any[]) => boolean) | undefined;

Expected

• editor.commands.updateSectionById({ id, html }) (and other extension commands) are typed and not possibly undefined.

Actual

• Extension commands are missing from the public EditorCommands type and are treated as possibly undefined.
