Summary

This PR updates the extractions/setup-just GitHub Action from v3 to v4 in the CI workflow. This is a routine dependency update issued by Renovate.

Verdict: ✅ Approved - This is a safe, low-risk maintenance update.

Research Notes

I reviewed the following sources:

1. Action Repository: The action is well-maintained with 148 stars and active development. The README shows identical usage syntax for v4 as v3.

2. Release v4 Notes: Released on April 5, 2026 (~1 month ago). No breaking API changes documented - the usage remains uses: extractions/setup-just@v4 with the same inputs (just-version, github-token).

3. Marketplace Listing: Confirms v4 is the latest stable version.

4. Repository audit: Only .github/workflows/ci.yaml uses this action - no other files need updating.

Suggested Next Steps

1. Merge this PR - No changes required. The update is backward-compatible at the usage level.
2. Monitor CI - As with any dependency update, watch the first CI run after merging to confirm the action works as expected (though risk is minimal).

General Findings

None. This is a clean, single-line dependency update with no issues identified.

Summary

This PR updates the extractions/setup-just GitHub Action from v3 to v4 in the CI workflow. The change is minimal (single line) and represents a routine dependency upgrade.

Verdict: Ready to approve — no issues found.

Research notes

I reviewed the following sources:

1. setup-just repository — The action is a well-maintained GitHub Action (148 stars) for installing the just command runner.

2. v4 release page — Released on April 5, 2026 by @rossmacarthur as version 4.0.0.

3. Comparison of action.yaml between v3 and v4:

   • v3 uses extractions/setup-crate@v1.4.0
   • v4 uses extractions/setup-crate@v2.0.0
   • All inputs (just-version, github-token) remain identical
   • No breaking changes to the public API or behavior

The major version bump appears to be driven by the underlying setup-crate dependency's major version change, not any breaking change in the setup-just action itself.

Suggested next steps

1. Merge this PR after standard CI verification passes.
2. Consider enabling Dependabot or Renovate auto-merge for minor/patch GitHub Actions updates to reduce review overhead for routine dependency bumps.

General findings

None. This is a straightforward, low-risk dependency update with no compatibility concerns.
