Note: this function intentionally does NOT resolve symlinks. A venv's
``bin/python`` is typically a symlink to the base interpreter (e.g. a
uv-managed CPython at ``~/.local/share/uv/python/.../python3.11``);
resolving that symlink swaps the unit's ``ExecStart`` to a bare Python
that has none of the venv's site-packages, so the service crashes on
the first ``import``. Keep the symlinked path so the venv activates
its own environment. Lexical expansion only via ``expanduser``.
