Detailed Description

Tiny persistent thread pool for parallel-for over short job ranges.

Designed for the per-frame "split this loop across N workers, wait for all to finish" pattern. Workers spin on a condition variable between jobs (no thread create / destroy churn), so the dispatch overhead is ~5–10 µs round-trip — small enough to be useful at 1000+ Hz frame rates for ranges that take more than a few µs of actual work.

Not a general-purpose scheduler: one job at a time, no priorities, no dependencies. Use it for parallel animation sampling, frustum culling, SoA component transforms, etc.
