CI: Latest dependency test failed (2026-03-02)

[github-actions]

Scheduled dependency compatibility check failed

The TestLatestDeps job failed when testing against the latest versions of all dependencies.

Workflow run: https://github.com/buckaroo-data/buckaroo/actions/runs/22566468864

This likely means a new release of a dependency introduced a breaking change.

Next steps

1. Check the workflow run logs to identify which dependency version caused the failure
2. Determine if this is a bug in buckaroo or the upstream dependency
3. If buckaroo needs a fix, create a branch and fix it
4. If upstream, consider pinning an upper bound temporarily in pyproject.toml
