Adds a histogram metric (
consensus_engine_beacon_time_between_new_payloads) to track the time interval between consecutiveengine_newPayloadcalls.Motivation
This metric helps monitor:
On mainnet with 12s slots, you'd expect ~12s intervals minus execution time. Deviations indicate missed slots or CL issues.
