Main shipped v1.37.0.0 (split-engine gbrain) while this PR was in review.
Merge resolved cleanly on bin/gstack-artifacts-init (allowlist patterns from
both branches coexist). CHANGELOG entry retained for our changes, version
header bumped from 1.36.0.0 to 1.38.0.0. Migration script renamed:
gstack-upgrade/migrations/v1.36.0.0.sh -> v1.38.0.0.sh, with internal
references and the test file updated to match.
VERSION + package.json: 1.38.0.0.
Regenerated SKILL.md across 12 hosts and refreshed golden fixtures.
