# Remove the per-job uv venv created by ci_install_dependency.sh.
#
# Meant to run in a post-job workflow step with `if: always()` so the venv is
# destroyed even on job failure/cancel. Runner-level safety net: a cron or
# startup task should also purge stale /tmp/sglang-ci-* directories to catch
# cancelled or crashed jobs that never reached this cleanup.
# Best-effort cleanup: never fail the job.
