typedoc renders re-exported type pages from the original-declaration
site (src/types/extensionTypes.ts), not from the @comfyorg/extension-api
barrel re-export. The shell-UI type aliases (ToastMessageOptions,
HotkeyExtension, AboutBadgeExtension, ToolbarButtonExtension) therefore
shipped to the dashboard without any @example blocks even though their
matching defineX entry points carry full examples in registrations.ts /
imperatives.ts.
Lift the canonical @example from each defineX onto the source
declaration so the dashboard type page renders with a working snippet.
Pure JSDoc — zero exported-type diff. Phase A freeze respected.
