# Self-heal the amaru venv. Runs at every workflow start; no-ops if the venv
# is already present and importable. Idempotent.
#
# Important: we deliberately verify by file presence inside the venv's own
# site-packages, NOT by `python -c "import …"`. A bare import can succeed
# against PEP 370 user-site or system packages even when the venv is empty,
# which produced silent under-installs in the past.
