name: Bump Plugin SHAs

# Nightly 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 per bumped plugin on branch `bump/<slug>`.
# Failing entries stay isolated in their own PR; passing bumps merge
# independently.
#
# Bot-free — uses the default GITHUB_TOKEN. PRs opened with GITHUB_TOKEN don't
# trigger on:pull_request workflows, so the required status checks on main
# (`scan` from Scan Plugins, `check` from Check MCP URLs, `validate` from
# Validate Plugins) would never run and the bump PR could never merge.
# workflow_dispatch is exempt from that recursion guard, so we dispatch all
# three ourselves against each per-entry bump branch after its PR is opened.
# Each check run lands on the branch HEAD — the same SHA as the PR head — and
# satisfies the corresponding required check. (Each of those workflows runs
# its job unconditionally on workflow_dispatch, so a dispatch always reports.)
#
# max-bumps caps the per-night work for cost control. Per-entry scans are
# more expensive than a single batched scan, so the cap is conservative.
# The composite action skips entries that already have an open bump PR, so
# re-dispatches don't pile up duplicate work.
