What Changed

• GOVULNCHECK_GO_VERSION: 1.27.2 → 1.27.3 (.github/env/00-core.env)
• The pull-request-management.yml workflow now also triggers on the synchronize event for same-repo PRs, so the "🔧 PR Management (Same Repo)" job runs on every new head commit.
• On synchronize runs, the label and default-assignee steps are skipped, and the job summary reports "None: new commits only". Concurrency for these runs uses a separate -push group, so a push right after a PR opens cannot cancel the run that labels it.
• Comments in the workflow header, trigger configuration, and concurrency sections were rewritten to explain the new behavior. Fork PR handling through the workflow_run path is unchanged and still fires only on opened, reopened, ready_for_review, or closed.

Why It Was Necessary

• A check run belongs to a single commit. If a ruleset requires the "PR Management (Same Repo)" check, any PR pushed to after opening would never get that check on its new head, which blocks the merge.
• Running the job on synchronize without re-applying labels or the assignee reports the check on each head commit. Maintainers can still override auto-applied labels without the workflow undoing their changes.

Testing Performed

• Reviewed the diff to confirm the synchronize guards on the label and assignee steps and the new summary branch.
• Confirmed the concurrency expression appends -push only when the action is synchronize, so those runs are grouped separately from opened/reopened/ready_for_review/closed runs.
• Behavior is best validated by pushing a commit to an open same-repo PR and checking that the check appears on the new head with no label or assignee changes.

Impact / Risk

• Risk: Low. The new trigger runs a mostly no-op job on each push, adding a small amount of CI usage per PR update.
• Fork PRs are not affected. Their pull_request runs skip the same-repo job, which satisfies a required check, and the fork path still uses workflow_run.
• No breaking changes. Existing behavior for opened, reopened, ready_for_review, and closed events is unchanged.
