Criterion benches over the M6-audit-named heaviest hot paths:
exo_time_crystal 256x128 autocorrelation, exo_ghost_hunter periodicity,
sec_weapon_detect per-subcarrier Welford, med_seizure_detect clonic rhythm
(medical-experimental-gated). Drives each through the public process_frame
on a fixed synthetic CSI frame after warming the relevant buffers.
Crate is workspace-excluded: run from the crate dir with --features std.
Set lib bench=false so libtest does not intercept criterion CLI flags.
HOST-MEASURED medians (Intel Core Ultra 9 285H, native --release), NOT the
ESP32/WASM3 doc budget (that needs hardware): time_crystal 17.3us,
ghost_hunter 1.44us, weapon 0.42us, seizure 0.10us.
Closes the ADR-160 deferred 'criterion benches for process_frame budget
claims' item on host. No production-code behavior change.
