… cleanup Replace all bare shutil.rmtree() calls in cli_deploy.py with a _robust_rmtree() helper that clears the read-only bit before retrying deletion on Windows. This prevents PermissionError ([WinError 5]) when cleaning up .git/objects after deployment. The fix is compatible with Python 3.10+ (uses onerror for <3.12 and onexc for >=3.12).

Summary
Fixes #4635
On Windows, files inside
.git/objects/are marked read-only by default. Whenadk deploycleans up the temporary directory in itsfinallyblock,shutil.rmtree()raisesPermissionError: [WinError 5] Access deniedon these files, causing the CLI to crash even after a successful deployment.This PR introduces a
_robust_rmtree()helper that passes an error handler toshutil.rmtree. On Windows, the handler clears the read-only bit (os.chmod(path, stat.S_IWRITE)) and retries the deletion. On non-Windows platforms,shutil.rmtreeis called without any handler. The fix usesonexcfor Python >= 3.12 andonerrorfor Python < 3.12 to avoid deprecation warnings.All six
shutil.rmtree()call sites incli_deploy.py(to_cloud_run,to_agent_engine,to_gke) are updated.Test Plan
