🐛 Fixes
Replace the old query planner with the incoming query planner on reload
We've fixed an important regression in v1.13.1 (introduced by PR #2706) which resulted in Routers failing to update to newer supergraphs unless they were fully restarted; hot-reloads of the supergraph did not work properly. This affects all v1.13.1 versions, whether the supergraph was delivered from a local file or if delivered as part of Managed Federation through Apollo Uplink.
