This issue tracks repair-button failures in CLI >= 2.77.0 caused by frame locals behavior changes (FrameLocalsProxy).
This PR adds focused regression coverage to lock in compatibility behavior in vm-repair parameter capture.

• Regression coverage: FrameLocalsProxy-safe parameter extraction
  • Added src/vm-repair/azext_vm_repair/tests/latest/test_repair_utils.py.
  • Verifies _get_function_param_dict(...):
    • materializes locals into a real dict
    • removes cmd
    • masks repair_password, repair_username, and encrypt_recovery_key
  • Simulates proxy-style locals via MappingProxyType + patched inspect.getargvalues.

proxy_locals = MappingProxyType({
    'cmd': object(),
    'vm_name': 'vm1',
    'repair_password': 'password',
})
with patch('inspect.getargvalues', return_value=ArgInfo([], None, None, proxy_locals)):
    values = _get_function_param_dict(frame=object())
