/**
 * Best-effort resident memory (bytes) of `rootPid` and all of its descendant

 * browser: browser + renderers + GPU) consumes, which the V8 JS heap does NOT.
 *
 * Purely additive observability: resolves to `null` on ANY failure (unsupported
 * platform, parse/permission error, missing tools, root process already gone).
 * Never throws to the caller. Browser builds always resolve `null`.
