Update Codemaps

Analyze the codebase structure and update architecture documentation:

1. Scan all source files for imports, exports, and dependencies

2. Generate token-lean codemaps in the following format:

   • codemaps/architecture.md - Overall architecture
   • codemaps/backend.md - Backend structure
   • codemaps/frontend.md - Frontend structure
   • codemaps/data.md - Data models and schemas

3. Calculate diff percentage from previous version

4. If changes > 30%, request user approval before updating

5. Add freshness timestamp to each codemap

6. Save reports to .reports/codemap-diff.txt

Use TypeScript/Node.js for analysis. Focus on high-level structure, not implementation details.
