Synchronize configuration files

Ensure all related configuration files are updated consistently when making changes to dependencies, versions, or other configuration settings. When updating a dependency version in one file (e.g., package.json), ensure that all related files (e.g., lockfiles, version specifications) are also updated to maintain consistency. This prevents subtle integration issues and build failures.

Example:

// When updating package.json
{
  "dependencies": {
    "browser-ui-test": "0.21.1",  // Updated from 0.20.6
    // other dependencies...
  }
}

// Also update related files like browser-ui-test.version to match

For build configurations, consider separating build artifacts from source code by copying configuration files to the build directory and running commands from there. This maintains source directory immutability during builds.
