This skill chains four skills in sequence:

1. /tech-debt -- inventory all technical debt in the codebase
2. /code-smell -- detect and fix code smells
3. /dead-code -- find and remove dead code
4. /iterate-review -- full review pass to harden the cleaned codebase

INPUT: $ARGUMENTS Pass a specific area to focus on, or leave empty for a full codebase sprint.
