[test] req-bump 2: no changeset + skip-changelog (expect check skipped/pass)

[DenKoren]

Validation PR for MILAB-6707 (github-ci @v4-beta require-package-path-bump gate). Points build.yaml at @v4-beta + enables the toggle. Do not merge — checking CI status only.

Expected: run / check for changesets skipped (== passing) due to the skip-changelog label.

Greptile Summary

This validation-only PR switches the build workflow to the github-ci v4 beta revision and enables its package-path version-bump gate to verify that the skip-changelog label skips the changeset check.

• v4-beta — The beta branch of the shared milaboratory/github-ci actions and reusable workflows. Both CI references change from the stable v4 branch to this beta branch for the validation.
• require-package-path-bump — A reusable-workflow boolean input requiring the package selected by package-path to include the expected version bump. It is newly enabled.
• package-path — The directory containing the package evaluated by the gate. It remains block, targeting the block package metadata.
• skip-changelog — A pull-request label expected to bypass the changeset/changelog check. This PR validates that the resulting check is skipped and therefore treated as passing.

Confidence Score: 5/5

No unacknowledged defect was identified in this validation-only workflow change, though the PR description explicitly says it must not be merged.

The workflow changes are consistent with the stated CI experiment, and the potentially persistent beta configuration is already explicitly acknowledged and excluded from merge.
