* chore: upgrade maintenance scripts to robust PyYAML parsing - Replaces fragile regex frontmatter parsing with PyYAML/yaml library - Ensures multi-line descriptions and complex characters are handled safely - Normalizes quoting and field ordering across all maintenance scripts - Updates validator to strictly enforce description quality * fix: restore and refine truncated skill descriptions - Recovered 223+ truncated descriptions from git history (6.5.0 regression) - Refined long descriptions into concise, complete sentences (<200 chars) - Added missing descriptions for brainstorming and orchestration skills - Manually fixed imagen skill description - Resolved dangling links in competitor-alternatives skill * chore: sync generated registry files and document fixes - Regenerated skills index with normalized forward-slash paths - Updated README and CATALOG to reflect restored descriptions - Documented restoration and script improvements in CHANGELOG.md * fix: restore missing skill and align metadata for full 955 count - Renamed SKILL.MD to SKILL.md in andruia-skill-smith to ensure indexing - Fixed risk level and missing section in andruia-skill-smith - Synchronized all registry files for final 955 skill count * chore(scripts): add cross-platform runners and hermetic test orchestration * fix(scripts): harden utf-8 output and clone target writeability * fix(skills): add missing date metadata for strict validation * chore(index): sync generated metadata dates * fix(catalog): normalize skill paths to prevent CI drift * chore: sync generated registry files * fix: enforce LF line endings for generated registry files
