* Enhanced CI/CD pipeline to test across multiple Node.js versions (20,
22, 24) and operating systems (Ubuntu, macOS).
  * Increased Node.js requirement to >= 20.
* Updated Egg.js framework and related tooling packages to beta
versions.
* Migrated projects to TypeScript and ES modules for improved type
safety.
  * Updated development dependencies and build tooling infrastructure.
