bench: refresh baseline.json — 20-core box, fe85197, rq-mutex

Browse Source 
Re-measured via jobrunner (taskset -c 0-19 of 24, rust:1.97-slim,
sweep.py run --save-baseline, 5 sets). Supersedes the old 24-thread
baseline; multi-thread labels are now 'smarm 20-thread'. Taken under
the rq-mutex default *before* the backend flip — the yield_many /
chained_spawn multi-thread regression reproduces here and is attributed
to rq-mutex contention (history.md session 5, finding 10).
