Updates:
- _INDEX.md: Added all 53 skills, updated total from 162 to 215
- CLAUDE.md: Updated Section 9 with new category summaries
- Created template file for consistent skill structure
- All skills have YAML frontmatter for agent compatibility
- All skills follow atomic skill guidelines (250-500 lines target)

Parallel execution via 7 sub-agents completed in ~3 hours
