Detailed Description

Two-way Layer-1 optimizer benchmark: plain Python vs the numba accelerator.

Serial in-process, one subprocess per condition, warmup discarded. "python" sets
ED_ACCEL=off so every candidate takes the authoritative Python path; "numba" runs
the accelerator. The C backend this once compared against was deleted after the
numba path overtook it.

Timing here is noisy enough that a single run is not a measurement: identical work
(seed pinned) has varied by 40% on a loaded box. Hence --reps and min/median.

Run: .venv/bin/python scripts/bench_layer1_numba.py --max-iterations 20 --reps 5

_pc()

Summarise N repetitions of one mode.

A single wall time is not a measurement here: on a loaded box the SAME work
(seed pinned, byte-identical candidate trajectory) was observed to vary
6.81s..11.59s, a 1.7x spread that dwarfs the C-vs-Numba difference. Report
min (least interference) and median instead.
