docs: measured PP link math (H=5120 verified, 20.5 MB/ubatch wire), NIC inventory

- Ethernet Bandwidth Math: new section 0 with live measurements
  (iperf 281-294 MB/s, ping RTT both paths, prefill 457.9 t/s at
  2.5GbE, per-ubatch wire 20.5 MB, 98k KV snapshot 3.45 GB blocking
  the slot 13.6 s, validated link-speed model: 386/458/505 t/s)
- System specs: NIC tables for both boxes; the 1 GbE USB-C adapter on
  the claw was silently routing the RPC path (unplugged 2026-08-17)
- PP Deployment: fix hidden-state size (10 KiB/direction, H=5120) and
  RTT-vs-bandwidth claim (decode RTT-bound; prefill+snapshot BW-bound)
