/**
 * `record_memory_tracking` (batch-14, soft-promoted from "推到 batch-14 nice")
 *
 * Pairs with `record_cpu_profile` to form the "性能三件套路线图" foundation
 * (cross-review v2.0.1 codex). Different signal:
 *   - `record_cpu_profile` → who (which JS function) is hot
 *   - `record_memory_tracking` → what (jsHeap / images / layers) is using memory
 *   - `record_timeline` → when (frame events) on the wall clock
 *
 * WIP: `Memory.startTracking` + `Memory.stopTracking` + `Memory.trackingUpdate`
 * events (probe-confirmed 2026-05-17).
 *
 * Apple's `Memory.trackingUpdate` payload contains a `categories` array
 * carrying per-bucket sizes (JavaScript / Images / Layers / Page / Other).
 * We sample the latest per category, then return delta vs initial sample.
