RFC 004 bench: spin_sweep measurement tool. Latency (p50/p90/p99/min/max, pooled across runs) vs idle-CPU (cores-busy via getrusage RUSAGE_SELF) over spin_budget_cycles x max_spinners x threads. Four workloads: remote-wake (latency target), fork-join, half-load (cost target), pure-idle (floor check). Env-knobbed SMARM_SPIN_*, greppable SPINCSV lines. Smoke-runs clean on 1 core (no hang); 1-core correctly shows the spinner-starves-producer pathology, real curve needs the many-core box.
