### <samp>🤖 Generated by Copilot at ebf2ff3</samp>
Added a deterministic version of `index_put` for MPS tensors that runs on a single thread and can be enabled by a global context flag. Refactored the existing `index_put` function and the kernel selection logic to support both parallel and serial modes. Added a test function to verify the deterministic behavior of `index_put` under different conditions.
