+ * Tests for issue #542: --jsdoc CLI parameter is not respected.
+ *
+ * Root cause: In commit bf53c43 (yargs v17→v18 upgrade), the CLI entry point was
+ * rewritten from the singleton pattern (yargs.option({...}).argv — which reads
+ * process.argv) to the factory pattern (yargs().option({...}).argv). The factory
+ * pattern creates a detached instance that does NOT read process.argv in either
+ * v17 or v18. The fix is to pass hideBin(process.argv) explicitly:
+ *   yargs(hideBin(process.argv)).option({...}).argv
