/**
 * Post-process execution events to improve timeline visualization:
 *
 * 1. Fire-and-forget child starts (`startChild`): set duration_ms = 0
 *    so they render as a narrow completed band instead of pending.
 *
 * 2. Completed signals (`waitFor` that received a signal): split into
 *    signal_wait_started + workflow_execution_signaled pair so the
 *    timeline can show the full wait duration as a band.
 *
 * 3. Running workflows: inject a pending signal_wait_started event
 *    after any fire-and-forget start that lacks a matching signal,
 *    so the timeline shows a growing orange "pending" band.
