KingIcyCreamProjects f72ee6532d resource_plan: count physical cores on Windows (GetLogicalProcessorInformationEx)
os.cpu_count() returns logical processors, so on SMT machines the plan
sets OMP_NUM_THREADS to 2 threads/core, which thrashes the AVX-512 units
during expert matmul (9950X3D: 32 logical vs 16 physical). Count
RelationProcessorCore records instead, with the existing lscpu/cpu_count
fallbacks intact.
