* Spawn the whole pool up front. The default demand-driven growth avoids * paying worker boot for small jobs, but a bulk index KNOWS every core will * be needed — on a fast repo the one-by-one ramp-up otherwise consumes most * of the parse phase (each worker boot is a fresh Node isolate + g

()

   * load, ~hundreds of ms, and growth only triggers as queue pressure builds).
