# Pre-warm the harness's uv script environment on the OPEN network.
#
# Runs in each workflow's `pre-agent-steps` — after checkout + Setup uv but
# before the firewalled agent step — into the same uv dirs the in-sandbox
# launcher uses, so the agent run reuses the warm cache instead of depending
# on PyPI access through the AWF firewall.
#
# Strictly non-fatal: on any failure the sandboxed `uv run --script` (with
# the `python` allowlist in each workflow) still installs from scratch.
