Binary Ninja fails to import editable (-e) packages from configured virtualenv

Version and Platform (required):

• Binary Ninja Version: 5.2.8275-dev (6bcfa4b7)
• Edition: Commercial
• OS: Debian
• OS Version: 12
• CPU Architecture: x64

Bug Description:
Packages installed in a virtual environment with the editable (-e) flag are not importable in Binary Ninja when the virtual environment’s site-packages is provided via the python.virtualenv setting.

Steps To Reproduce:

1. Follow the development installation instructions for Mole (editable install, e.g., pip install -e .).
2. Configure Binary Ninja to use your virtual environment via the python.virtualenv setting so that its site-packages is on the module search path.
3. Start Binary Ninja and try to import mole → ModuleNotFoundError: No module named 'mole'.
4. Open the Python interpreter within the same virtual environment; import mole succeeds.

Expected Behavior:
Binary Ninja should resolve and import packages installed with the editable (-e) flag exactly as it does for non-editable installs.

Reproduce the issue using the development installation instructions in docs/01-Installation.md, an editable install, and Binary Ninja's python.virtualenv setting. Compare import behavior in Binary Ninja's Python interpreter with the same virtual environment's interpreter. Done means editable packages import successfully in Binary Ninja as non-editable packages do.
