/**
 * OpenKernel — Event Bridge
 *
 * Taps the kernel EventBus (via subscribeAll) and turns local events into
 * compact StreamFrames the mesh broadcasts to connected harnesses. Tuned for
 * animation: lifecycle events flow immediately (so the map reacts instantly),
 * while noisy LOG/PROVIDER_HEALTH chatter is coalesced on a short flush timer to
 * keep the byte-rate low.
