Memory series

The initial RSS steps remain visible. A later quiet reproduction records per-mapping RSS and huge-page promotion; see the memory finding in the review notes. No smoothing or subtraction hides allocator/kernel overhead. Other workloads have different rates/rings/generator revisions; compare them as separate scenarios.
