solve #141
The recent commit optimizes the internal test runner logic by ensuring TestSuiteGate correctly initiates pytest subprocesses. We transitioned the execution pipeline away from hardcoded "python3" strings to seamlessly utilize the native sys.executable, which inherently forces the subprocess to inherit the exact host environment, resolving potential mismatches with virtual environments or system Python installations. Additionally, instead of defaulting the execution working directory (cwd) contextually to the parent folder of whatever file was changed, the engine now dynamically detects and elevates the execution path to the base project_root or search_root. This crucial adjustment ensures that global configurations—such as pytest.ini, conftest.py, nested tool.pytest logic inside pyproject.toml, and native PYTHONPATH parameters—are successfully discovered and loaded correctly during the initial collection phase, greatly improving execution reliability across diverse repository architectures.
