ywkang 5fdb6f8797 Latency model: HBM PC striping + chunk-loop drain (ADR-0033) ...

Previous model double-counted slow-upstream paths (e.g., 64KB via UCIe
128 GB/s was ~2x pessimistic). HBM CTRL now distributes bursts across
8 pseudo-channels via global round-robin, with per-chunk commit timing
that pipelines correctly against the bottleneck link's data arrival.
