/**
 * BrainTelemetryBridge — forwards local Brain (decision layer) events to the
 * HQ publisher as `brain.event` envelopes, so the command center can observe
 * decision requests, answers, denials, ask-human escalations, and
 * self-activated interventions across every connected machine.
 *
 * Source: the `brain.*` EventBus events emitted by `ObservableBrainArbiter`
 * (`coordination/brain.ts`) and `BrainMonitor` (`coordination/brain-monitor.ts`).
 * All payloads are plain serializable data (request id, question, source, risk,
 * decision kind, rationale) — no closures, no decoupled relay needed.
 *
 * The webui `setup-events.ts` already forwards these verbatim to its browser;
 * this bridge does the same for the cross-machine HQ plane.
 *
