fix: auto-update ChromeDriver when version mismatches Chrome

Add version compatibility check before using existing ChromeDriver. When the installed ChromeDriver major version does not match Chrome, chromedriver_autoinstaller downloads the correct version automatically instead of failing with a version mismatch error. Add helper functions get_chromedriver_version() and is_chromedriver_compatible() with tests for version matching logic.
