Simplify Code — Parallel Review & Cleanup

Review your recent code changes with three focused reviewers running in parallel, aggregate their findings, and apply the fixes worth applying.

Core principle: Three narrow reviewers beat one broad reviewer. Each one deeply searches the codebase for a single class of problem — reuse, quality, efficiency — without diluting its attention across all three. They run concurrently, so you pay the latency of one review, not three.
