name: Bump plugin SHAs

# Weekly sweep of marketplace.json — for each entry whose upstream repo has
# moved past its pinned SHA, open a PR against main with updated SHAs. The
# validate-marketplace workflow then runs on the PR to confirm the file is
# still well-formed.
#
# Adapted from claude-plugins-community-internal's bump-plugin-shas.yml
# for the single-file marketplace.json format. Key difference: all bumps
# are batched into one PR (since they all modify the same file).
