React Compiler in the Extension UI: what it optimizes, where it bails out, and when manual memoization is still needed. Use when deciding whether `useMemo`, `useCallback` or `React.memo` are still required, reviewing reflexive memoization, or working out why a component isn't optimized. Dependency arrays go to `perf-hooks-effects`.
