bench: pin cores + read h2load -m1 as latency, not throughput

The h2load switch surfaced a scary 626k(direct) vs 188k(proxied) req/s.
It was a measurement artifact, not a zoxy regression:

- -m1 is closed-loop (1 req/conn), so req/s = conns/mean-latency — it
  measures LATENCY. A proxy adds a hop, so proxied req/s drops by
  construction; on loopback there is no RTT to hide the ~11us hop behind.
- The default run oversubscribed CPU: zoxy spawns one worker per visible
  CPU, so 8 zoxy + 4 nginx + 4 h2load = 16 hot threads on 8 cores while
  the direct baseline ran only 8. That alone inflated the hop 2-3x.

Fixes to the script:
- taskset each role to disjoint cores (origin smallest — canned 200;
  proxy + generator split the rest). zoxy is sized by its visible-CPU
  count, so taskset both pins and sizes it. Same origin/gen cores in
  every run, so the only variable is the hop.
- sample zoxy's per-run CPU via /proc/PID/stat and print it — headroom
  proves the loop is latency-bound, not saturated.
- quiet h2load to the throughput line, request tally (failed/errored
  tripwire), and latency table; add a "reading the result" note.

Pinned 2/3/3 on the 8-core box: 323k direct vs 213k proxied (~1.5x),
zoxy 119% of 300% available, 99.99% upstream reuse, 0 errors.
