name: Bump Plugin SHAs

# Weekly sweep: for each external entry whose upstream HEAD has moved past
# its pinned SHA, validate at the new SHA with `claude plugin validate`
# inline, then open one PR with all passing bumps.
#
# Bot-free — uses the default GITHUB_TOKEN. PRs opened with GITHUB_TOKEN don't
# trigger on:pull_request workflows, so the policy scan (`Scan Plugins`, a
# required status check on main) would never run and the bump PR could never
# merge. workflow_dispatch is exempt from that recursion guard, so we dispatch
# the scan ourselves on the bump branch after the PR is opened. The check run
# lands on the branch HEAD — the same SHA as the PR head — and satisfies the
# required check.
