Custom Taxonomy Registration
Registers three hierarchical taxonomies for categorizing and filtering references:
- reference-type: Main categorization for references (e.g., Web Development, Design)
- reference-filter-1: First custom filter dimension (project-specific)
- reference-filter-2: Second custom filter dimension (project-specific)
All taxonomies support hierarchical organization and are available for filtering in both admin and frontend contexts.
