v0.2.45

Promote self-heals a stale scaffolded merge.yml before merging: mergeFeature runs a best-effort pre-merge workflow refresh (defaultRefreshPromoteWorkflows) so a project whose merge.yml still calls 'lakebase-schema-migrate apply' against the parent tier gets the corrected 'apply-tier' step into the merge commit — CI passes and cleanup runs. Never blocks the merge. lakebase-doctor names the apply->apply-tier skew.
