Code Review
This pull request implements synchronization for the block_size parameter between the engine core and the client. The EngineCoreReadyResponse was updated to include block_size, and the MPClient now updates its local configuration using the maximum value received from the engines to ensure consistency, particularly for hybrid Mamba models. A new unit test verifies this behavior. I have no feedback to provide as there were no review comments.
