Closing as part of the 2026-05-20 GitHub audit pass. Tracked alongside the other three major-version dep bumps at #45 so the open-PR list stays clean for visitors. Dependabot will re-open this on its next scheduled run (Mondays 09:00 CT); the migration work belongs on a dedicated branch with its own validation pass.

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.
