feat(cua): release 0.38.0+artemis.1 with verified shell observation

Upgrade the pinned driver, validate menu and taskbar focus ownership, patch untitled Shell resolution, and remove duplicate scroll scaling. Publish package provenance, verification boundaries and matching marketplace checksum. Go tests, vet, build and byte-level package verification passed.
