This commit removes several utility modules used for debugging, memory inspection, and hardware information gathering. These tools are no longer required and their removal simplifies the codebase. The following files have been deleted: - `debug_utils.py` - `device_memory_audit.py` - `hardware_info.py` - `model_sig.py` Additionally, the call to log memory usage on startup has been removed from `__init__.py`.
