fix(localsearch): resolve move_thread_count when the phase solves - #224
Merged

Conversation
Lowering a local-search phase resolved move_thread_count through rayon::current_num_threads(), which starts the global Rayon pool when called outside one. Compiling any runner with an acceptor-forager local search and the default move_thread_count = "auto" therefore spawned a thread per core before anything was solved, and the policy followed the pool the runner was compiled in rather than the one the phase solves in. The lowered phase now keeps the configured MoveThreadCount and resolves it when it solves, on the pool it solves in. The cartesian gate case, which compiles a local-search runner without solving it, starts no threads again, and its allocation counts match v0.24.0 in every trial. Closes #221
