Generates product-local runtime task metadata lookup functions.

The generated module exposes:

• DEFINITIONS
• as_str(kind)
• display_name(kind)
• presentation_code(kind)
• from_wire_value(value)

This keeps runtime task wire values, display names, and presentation codes registered in one product-local place while preserving product-owned enums and UI codes.
