Changes

Dependabot Go dependency grouping

Layer / File(s)	Summary
Go dependency group patterns .github/dependabot.yml	The Dependabot groups configuration replaces dependency-type-based dev/prod entries with test-dependencies patterns for github.com/onsi/ginkgo* and github.com/onsi/gomega*, plus a prod-dependencies exclusion list for those same packages.

Stable And Deterministic Test Names	✅ Passed	No Ginkgo titles use dynamic data; the only test titles are static literals in version/version_test.go, and this PR only changes dependabot config.
Test Structure And Quality	✅ Passed	PR only changes .github/dependabot.yml; no Ginkgo test code was modified, so this test-quality check is not applicable.
