fix (test): use TCP healthcheck for MySQL containers to prevent flaky startup#64
Merged
Conversation
MySQL treats "localhost" as a Unix socket connection, which can be ready before the TCP listener. Dependent services connecting over TCP would intermittently get "connection refused". Switching to 127.0.0.1 forces TCP-based healthchecks, matching the actual connection path. Also removes retry loop from ConnectMySQLService since the healthcheck now guarantees TCP readiness.
