Spec structure and tooling refresh
Built-in function annotations — A broad markup pass now labels many clause entries as type="built-in function", improving spec classification and generated output structure.
ecmarkup 24.0.0 upgrade — The build pipeline was bumped to ecmarkup 24.0.0, along with the matching biblio update to 2.2.x.
Other misc changes
Editorial and maintenance fixes — Minor wording cleanup in algorithms around unset parameters and host-defined data, plus another legacy IPR override entry added to the form-checking script.
