refactor(skills): Restructure skills to dual-platform architecture

Major refactoring of ourdigital-custom-skills with new numbering system:

## Structure Changes
- Each skill now has code/ (Claude Code) and desktop/ (Claude Desktop) versions
- New progressive numbering: 01-09 General, 10-19 SEO, 20-29 GTM, 30-39 OurDigital, 40-49 Jamie

## Skill Reorganization
- 01-notion-organizer (from 02)
- 10-18: SEO tools split into focused skills (technical, on-page, local, schema, vitals, gsc, gateway)
- 20-21: GTM audit and manager
- 30-32: OurDigital designer, research, presentation
- 40-41: Jamie brand editor and audit

## New Files
- .claude/commands/: Slash command definitions for all skills
- CLAUDE.md: Updated with new skill structure documentation
- REFACTORING_PLAN.md: Migration documentation
- COMPATIBILITY_REPORT.md, SKILLS_COMPARISON.md: Analysis docs

## Removed
- Old skill directories (02-05, 10-14, 20-21 old numbering)
- Consolidated into new structure with _archive/ for reference
