fix: resolve GitHub Actions test failures for Node.js 18.x and 20.x

Fixed the ERR_UNKNOWN_FILE_EXTENSION error that was causing test failures
in GitHub Actions for Node.js 18.x and 20.x while maintaining compatibility
with Node.js 22.x.

Root cause:
- Node.js 18.x and 20.x have stricter ESM module handling compared to 22.x
- The ts-node configuration wasn't properly set up for cross-version compatibility

Changes made:
1. Updated tsconfig.dev.json with better ESM configuration:
   - Added transpileOnly: true for faster compilation
   - Explicit module settings for better ESM support
   - Added module: "ESNext" and moduleResolution: "node"

2. Updated package.json dev script:
   - Added --transpileOnly flag for better compatibility

Verification:
✅ All tests now pass on Node.js 18.x, 20.x, and 22.x
✅ Development mode works correctly
✅ Production mode works correctly
✅ Build process works correctly

This fix ensures backward compatibility while maintaining all existing functionality.
