RCS Selector Benchmark (extended)

Compare four patterns using react-concurrent-store:

• useStore + derive in render (baseline) — Raw useStore, no selector, no compiler
• useStore + derive in render (global shared selector) — useStore with global memoized selector
• useStoreSelector (shared selector) — Raw useStoreSelector
• Precompute on write — reducer computes derived view; reads are O(1)
