ExampleMetadata

type ExampleMetadata = ExampleMetadataRegistry extends { metadata: infer T }
  ? T
  : Record<string, unknown>;

Resolved example metadata type.

If ExampleMetadataRegistry has been augmented with a metadata property,
this resolves to that type. Otherwise, falls back to Record<string, unknown>.

This allows the generate command to provide project-specific types that
automatically apply to all Example types without explicit generic parameters.
