Split out of #21240. Stacked on #21249 (review/merge that first).
Concurrent `syncApplication` calls on the same workspace could
interleave their metadata migrations and leave metadata partially
applied. Wrap the manifest sync in a per-workspace cache lock
(`app-sync:<workspaceId>`), mirroring the install path. The rate-limit
throttle stays outside the lock.
