Primitive metrics for LiveNode::run dispatch and loop work after startup.

Rates, mean dispatch time, backlog pressure, and utilization are derived by callers from successive snapshots. Values reset each time LiveNode::run enters steady state. Residual channel dispatch during shutdown grace is included, but the final post-loop drain is not. Snapshots are lock-free and may not be a consistent cross-field view.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

time_events: RunnerChannelMetricsSnapshot

Time event channel metrics.

exec_events: RunnerChannelMetricsSnapshot

Execution event channel metrics.

exec_commands: RunnerChannelMetricsSnapshot

Execution command channel metrics.

data_events: RunnerChannelMetricsSnapshot

Data event channel metrics.

data_commands: RunnerChannelMetricsSnapshot

Data command channel metrics.

dispatch_busy_ns: u64

Cumulative nanoseconds spent in the five dispatch branches.

maintenance_busy_ns: u64

Cumulative nanoseconds spent in maintenance and reconciliation report processing.

external_msgbus_busy_ns: u64

Cumulative nanoseconds spent handling external message bus ingress.

elapsed_ns: u64

Monotonic nanoseconds since the steady-state runner loop started.
