preact-missing-hooks/scripts/generate-entry.cjs

A lightweight, extendable collection of missing React-like hooks for Preact — plus fresh, powerful new ones designed specifically for modern Preact apps.

 * Generates dist/entry.cjs which auto-detects Preact vs React at runtime (CJS only).
 * Run after build so dist/index.js and dist/react.js exist.
