Detailed Description

Snapshot of basic CPU/NUMA topology.

Value type (copyable). Populated by read_topology().

• cpu_count: total logical CPUs (from std::thread::hardware_concurrency).
• numa_nodes: number of NUMA nodes (always 1 on Windows; detected via /sys/devices/system/node/ on Linux).
• node_to_cpus: mapping from NUMA node index to the set of logical CPU indices belonging to that node.
