Detailed Description

Per-thread accumulator for timing and counters.

All hot-loop work writes only into its own thread's instance (plain, non-atomic adds), and the engine reduces these into the shared totals once per step. This removes the per-input atomic contention that previously serialized high core counts.

Aligned (and implicitly sized) to a cache-line multiple so that adjacent threads' accumulators never share a cache line (no false sharing).
