Review Refactors

Hunt for the mid-to-long-term simplest, most elegant design — deep structural simplifications, not surface cleanups. Explicitly discounts "that's more code / more work to build" as an objection, so it argues for the best long-term shape even when it means large rework. Given no target it triages the repo itself (churn, defect density, size, crusted code, centrality) and picks the highest-payback hotspots. Produces a tiered, blast-radius-tagged proposal list; applies only what the user approves. Use when the user asks where the code could be built simpler/more elegantly/better, wants refactoring opportunities, wants technical debt reduced, or wants duplication removed acro…
