# We do NOT add the venv Scripts dir to PATH (it also holds python.exe
# and pip.exe, which would hijack the user's system interpreter).
# Hardlink preferred; falls back to copy if cross-volume or non-NTFS.
#
# Clean up the legacy venv Scripts PATH entry that older installers wrote.
# Without this, upgrade users keep python/pip hijacked even after the shim
# approach is in place.
