What changed

Add opt-in initial heartbeats for Go remote payload activities and a separate child payload-size distribution to throughput_stress. Unset options preserve the existing heartbeat behavior and child inheritance.

Why

OSS Nightlies calibration needs to preserve heartbeat pressure and positive child payloads while matching the legacy zero-byte root payload. One global payload setting cannot express that workload.

Details worth reviewing

Local activities do not emit heartbeats. These controls do not select or activate a Nightlies profile; quantitative tuning and final-profile qualification remain separate.

Superseded by #519 (healthy heartbeating activities). The child payload control is dropped.
