feat: add GTM editor & validator skills (61, 62), update GTM audit (60)
Restructure GTM skills into audit → edit → validate workflow:
- 60-gtm-audit: MCP-based page scan, site audit, gap analysis, tag design (new code/SKILL.md)
- 61-gtm-editor: tag/trigger/variable creation via GTM API, ES5 Custom HTML, dataLayer generation
- 62-gtm-validator: QA toolkit with 7 validation modes, naming conventions, cross-platform mapping
All three skills use DTM Agent + Chrome DevTools MCP with clear handoff patterns.
