+synopsis:       End-to-end ChuSQL benchmarks over TCP
+description:    Starts a chusql-server process and benchmarks authentication,
+                ping, catalog access, and queries through the newline-delimited
+                JSON TCP protocol. Uses the TCP client and shared protocol models;
+                query execution and storage remain in the server process.
