What changed in this version

• Fixed incorrect attribute groups appearing on category pages when those terms were not actually assigned to products in the current category archive.
• Scoped faceted count queries to the current product category and active archive, preventing unrelated attributes from remaining visible in the widget.
• Improved category detection by falling back to the URL slug when the queried taxonomy object is not available yet during archive rendering.
• Hardened input sanitization and request parsing to satisfy WordPress security checks and reduce false-positive warnings.
• Cleaned up query-layer SQL handling for dynamic joins and filtered counts without changing plugin behavior.
• Removed frontend debug output and related temporary hooks used during diagnostics.
• Updated plugin metadata and readme consistency to align with Plugin Check recommendations and WordPress.org compatibility checks.
