Rongsong Shen 7dc657b1bd feat(ha-repl-hardening): populate stateReport in standby heartbeat reply (task 2.3) 
OPCode_nop handler now sends stateReport {applied_lsn, config_tag}
instead of nodata. Function in ha.c for unit-test linkability.
Two tests: warm state and zero-state fresh standby (Req 1.4).
