name: Install & Update E2E (reusable)

# Runs ONE update route against ONE starting commit, in the dev sandbox, with a
# real install (uv, a managed Python, Node, the venv) behind it.
#
# Reusable so callers can fan out over the combinations that matter -- update
# from the tip vs. from an older release, `hermes update` vs. re-running the
# installer -- without duplicating the runner setup. Each leg is independent:
# its own sandbox, its own install, nothing rewound or shared.
#
# Call it:
