description	Scan codebase for tech debt: duplicated logic, dead code, magic numbers. Use at end of session before final commit for a broad codebase sweep. NOT for reviewing only recently changed code (use /simplify).

Scan recently changed files (git diff --name-only HEAD~5) for:

1. Duplicated logic — consolidate into shared utility
2. Dead code — unused imports/exports/functions (grep to verify before removing)
3. Magic numbers/strings — extract to named constants
4. Nested conditionals >3 levels — refactor with early returns
5. TODO/FIXME — list but don't auto-fix without asking

For each finding: file:line, category, description, proposed fix Ask before applying fixes that touch >3 files. After fixes: run the project's type checker or linter to confirm no regressions.
