- Updated `ref_program` in `benchmark_matmul.py` to remove the unused parameter `C`, simplifying the function signature.
- Changed logging level in `autotuner/__init__.py` from `INFO` to `DEBUG` for more detailed logging during autotuning.
- Modified the error handling in the autotuner to provide clearer messages and log errors at the debug level.
- Enhanced error reporting in the JIT adapter by adding detailed context to error messages in `cython_wrapper.pyx` when kernel calls fail.
