Incremental Code Review Summary

Reviewed the latest PR head after the workflow-generation fixes. Both previously reported issues are resolved: the CLI-generated reusable caller now derives its labeled-event condition from whether the configured label value is present, and the skills installer now emits the labeled/closed triggers plus the required-labels forwarding. I resolved both stale review threads before submitting this review.

The latest diff also updates all localized workflow snippets, expands installer and builder tests for label-trigger behavior, and preserves the case-insensitive OR matching in the gate implementation. No additional confirmed bugs were found by the available review workers. Risk level: standard. 🧪 Browser testing: Skipped — PR only modifies backend/config/docs/tests, no UI impact.
