Use cross-platform build commands

Replace native shell commands in package.json scripts with cross-platform alternatives to ensure build consistency across different operating systems. Native commands like rm -rf fail on Windows, breaking CI/CD pipelines that run on mixed environments.

Use tools like shx or rimraf instead of native shell commands:

{
  "scripts": {
    // ❌ Not cross-platform compatible
    "clean": "rm -rf build",
    "build": "rm -rf dist && rslib build && chmod +x dist/*.js",
    
    // ✅ Cross-platform compatible
    "clean": "shx rm -rf build", 
    "build": "shx rm -rf dist && rslib build && shx chmod +x dist/*.js"
  }
}

This ensures your build scripts work reliably in CI/CD environments regardless of the underlying operating system, preventing deployment failures due to platform-specific command incompatibilities.
