Add scripts for resolving and verifying Chromium binary paths

- Implemented `chrome-path.js` to define functions for locating Chromium binaries across different platforms and nested directories.
- Added `verify-chromium.js` to check for the presence of the Chromium binary and log the results, including candidate paths checked.
- The scripts support Linux, Windows, and macOS environments, enhancing the flexibility of Chromium binary detection.
