test(internode): pin msgpack gate rollback coverage (#5203)

Add test coverage for the msgpack-only request/fleet confirmation truth table and exact request JSON policy manifest.

Pin request and response rollback behavior so removing either gate restores JSON compatibility while both gates enter msgpack-only for eligible fields.
