refactor: Reorganize skill numbering and update documentation

Skill Numbering Changes:
- 01-03: OurDigital core (was 30-32)
- 31-32: Notion tools (was 01-02)
- 99_archive: Renamed from _archive for sorting

New Files:
- AGENTS.md: Claude Code agent routing guide
- requirements.txt for 00-claude-code-setting, 32-notion-writer, 43-jamie-youtube-manager

Documentation Updates:
- CLAUDE.md: Updated skill inventory (23 skills)
- AUDIT_REPORT.md: Current completion status (91%)
- Archived REFACTORING_PLAN.md (most tasks complete)

Removed:
- ga-agent-skills/ (moved to separate repo ~/Project/dintel-ga4-agent)

+name: notion-organizer
+description: Notion workspace management agent for organizing, restructuring, consolidating, and maintaining databases and pages. Use when user asks to search Notion, organize databases, clean up properties, migrate data, merge databases, audit schemas, or manage Notion content. Activates for keywords like Notion, database, knowledge base, wiki, workspace organization.
+allowed-tools: mcp__notion__*, Read, Write, Edit, Bash(python:*), Bash(pip:*)

+# Notion Organizer Skill
+
+## Purpose
+
+Specialized Notion workspace management capability for:
+- Database schema analysis and optimization
+- Property standardization and cleanup
+- Content restructuring and hierarchy optimization
+- Database merging and migration
+- Bulk operations with rate-limit compliance
+
+## Execution Strategy: Three-Tier Approach
+
+Always follow this priority order:
+
+### Tier 1: Notion MCP Tools (Primary)
+
+Use built-in MCP tools first. Available tools:
+
+| Tool | Purpose |
+|------|---------|
+| `mcp__notion__search` | Find pages/databases by keyword |
+| `mcp__notion__get-page` | Retrieve page content |
+| `mcp__notion__get-database` | Retrieve database schema |
+| `mcp__notion__create-page` | Create new pages |
+| `mcp__notion__update-page` | Modify page properties |
+| `mcp__notion__query-database` | Query database with filters |
+
+### Tier 2: Alternative Approaches (Fallback)
+
+If MCP tools insufficient:
+- Export/import via filesystem (user action required)
+- Memory tools for tracking state across sessions
+- Sequential thinking for complex planning
+
+### Tier 3: Python Scripts (Advanced)
+
+For bulk operations (50+ items):
+- Generate async Python scripts
+- Include rate limiting (3 req/sec max)
+- Provide requirements.txt
+- Always include dry-run option
+
+See `scripts/` directory for templates.
+
+## Operational Guidelines
+
+### Before Any Modification
+1. **Fetch first**: Always examine current structure before changes
+2. **Confirm destructive actions**: Get user approval for deletes/major restructures
+3. **Estimate impact**: For large operations, provide time/API call estimates
+4. **Backup reminder**: Remind about Notion version history
+
+### Rate Limits (Critical)
+- Maximum: 3 requests/second average
+- Use pagination (100 items max per request)
+- Implement exponential backoff on 429 errors
+
+### Communication
+- Korean for explanations (한국어로 설명)
+- English for code and technical terms
+- Structured before/after summaries
+
+## Quick Commands
+
+### Database Audit
+"Analyze [database name] structure and recommend optimizations"
+
+### Property Cleanup
+"Standardize property names in [database] to [convention]"
+
+### Bulk Move
+"Move all pages tagged [X] from [source] to [target]"
+
+### Schema Migration
+"Migrate data from [source database] to [target database]"
+
+## Workflow Patterns
+
+See `reference.md` for detailed workflow documentation.
+See `scripts/` for Python templates.
+
+## Limitations
+
+- Cannot access unshared databases/pages
+- Cannot modify workspace settings
+- Cannot recover permanently deleted content
+- Large operations (1000+ pages) require Python scripts
