Adds a conftest.py pytest fixture to explicitly clear the lru_cache for bash detection, addressing the monkeypatching hazard in a way that doesn't rely solely on comments. (Note: CI currently runs python -m unittest, but this keeps local pytest runners safe.) Also updates the bash check to run the execution probe directly inside the cached _check_bash_state, exposing the difference between 'no bash found' and 'bash present but execution failed' directly to the unittest skip reason.
