Closing under the security-only posture (ADL-32 ruling 2026-08-19). The bundler version lane is now at open-pull-requests-limit: 0, so this bump will not be re-proposed — closing it is the decision that it doesn't happen. Gems on this repo now move on a security advisory or a deliberate hand-run bump. The github-actions lane is unaffected and stays at limit 10.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
