Pull request overview

Fixes create_labels label discovery by expanding compile-time JSON label aggregation to include on.label_command trigger labels, preventing missing-label scenarios during admin label creation.

Changes:

• Expanded extractSafeOutputLabels to collect labels from WorkflowData.LabelCommand in addition to safe-outputs label sources.
• Adjusted nil-handling so label extraction still works when SafeOutputs is absent.
• Added unit tests for inclusion and cross-source deduplication behavior.

• The primary bug scenario described in the PR is workflows that use on.label_command but have no safe-outputs config (i.e., SafeOutputs is nil). The current tests only cover cases where SafeOutputs is non-nil. Add a test that sets SafeOutputs: nil and LabelCommand: []string{"deploy"} and asserts the label is still returned.

func TestExtractSafeOutputLabels_IncludesLabelCommand(t *testing.T) {
	data := &workflow.WorkflowData{
		SafeOutputs: &workflow.SafeOutputsConfig{
			CreateIssues: &workflow.CreateIssuesConfig{
				Labels:        []string{"bug"},
