Greptile Summary

This PR lifts the PHP version ceiling in composer.json from <8.3 to <8.4 and adds PHP 8.3 to the CI test matrix, unblocking the wings-api 8.3 upgrade. The constraint and CI coverage are aligned — every permitted PHP version (7.4 through 8.3) is exercised in CI.

• composer.json: "php": ">=7.4 <8.3" → "php": ">=7.4 <8.4". Note: the PR title and description reference <8.5, but the actual change is the more conservative <8.4, which matches CI coverage exactly.
• .github/workflows/pr_test.yml: "8.3" added to the PHP matrix; combined with prefer-lowest and prefer-stable composer variants, the new version gets thorough dependency coverage.

Confidence Score: 5/5

Safe to merge — the two-line change correctly narrows the ceiling to <8.4 and adds 8.3 to CI, giving full coverage of every permitted PHP version.

Both changed files are configuration only. The composer constraint and CI matrix are perfectly aligned: every PHP version the package now accepts (7.4 through 8.3) is exercised in CI with both prefer-lowest and prefer-stable dependency variants. No runtime code was touched.

No files require special attention.

The red 8.3 CI legs are expected and not a fault in this PR: composer resolution fails because the released rexlabs/utility-belt 4.0.0 still caps php <8.3. Once utility-belt-php#3 merges and tags, re-running this PR's CI should go green — please merge/tag that one first.
