Refactor Clean

Safely identify and remove dead code with test verification:

1. Run dead code analysis tools:

   • knip: Find unused exports and files
   • depcheck: Find unused dependencies
   • ts-prune: Find unused TypeScript exports

2. Generate comprehensive report in .reports/dead-code-analysis.md

3. Categorize findings by severity:

   • SAFE: Test files, unused utilities
   • CAUTION: API routes, components
   • DANGER: Config files, main entry points

4. Propose safe deletions only

5. Before each deletion:

   • Run full test suite
   • Verify tests pass
   • Apply change
   • Re-run tests
   • Rollback if tests fail

6. Show summary of cleaned items

Never delete code without running tests first!
