refactor
by peth-eth
Maintenance-day runner — deletes dead weight (legacy, deprecated, AI slop, stubs, bad comments), then runs jscpd, knip/vulture, madge (circular deps), ESLint/Biome/ruff, fixes weak types properly (research + replace), removes unjustified try/catch, consolidates shared types, and scans for structural issues. Language-agnostic. Use when paying down tech debt or doing periodic cleanup.
