bin/sage run js/scripts/push-all.js takes a long time after grunt sync --allBranches

Used to be < 100ms and now is closer to 10s. This is a big drag since I run this script extremely frequently.

# clean-active-repos.sh
#
# Reads ./perennial/data/active-repos (one repo path per line)
# and, for each repo:
#   • checks out `main`
#   • force-deletes every other local branch
#   • prunes stale remote-tracking refs
#   • runs an immediate GC to reclaim space
#
# If a repo has no `main` branch it is left untouched (with a warning),
# so you can adapt later if some projects still use `master`, etc.

Well, I pruned the branches and it is still taking a long time. So I'm not sure what may have caused it or how to speed it up.

Self-unassigning for now, I'll return if the delay is causing problems in the future.
