The bootstrap that used to run in a dedicated recovery Job now happens in-process inside the instance pod before PostgreSQL starts, so the sidecar shipped in that pod must answer the same Restore RPC the operator sends over the plugin sockets. The instance mode now registers the restore job hooks and advertises the restore-job service capability so the operator can reach them. A cluster that only bootstraps from an object store, without continued archiving, previously received no sidecar in its instance pods; the injection condition is widened to match what the plugin configuration already considers valid, so those clusters get the sidecar too.
