/**
 * toolEndEmitter — shared helper for emitting `tool:end` events from
 * AI-SDK `onStepFinish` callbacks.
 *
 * Pipeline B (metrics aggregator) listens for `tool:end` on the NeuroLink
 * EventEmitter. When tools are executed by the AI SDK internally (via
 * `generateText` / `streamText`) the SDK calls `onStepFinish` with the
 * completed tool results. Without this helper those results are silently
 * stored but never surfaced as `tool:end` events, leaving Pipeline B with
 * zero tool spans for AI-SDK-driven tool calls (gaps G5 and S2).
