Fix phar path resolution by using Phar::running(false) for WP_CLI_ROOT

Replace hardcoded 'phar://wp-cli.phar' with dynamic Phar::running(false) to correctly handle renamed phar files. This ensures WP_CLI_ROOT always points to the actual phar stream path, fixing template path resolution when the phar is not named 'wp-cli.phar'.
