// ============================================================================
//  NodeSimulator - virtual nodes that generate sample audio in software.
//
//  Implements NodeSource so the CollectionService feeds simulated PCM through
//  the exact same path as real UDP nodes. Each virtual node emits a distinct
//  sine tone per mic plus a small DC marker per node, so channel -> track
//  mapping is easy to verify in the WAV on a PC.
//
//  Enable/disable with NET_SIM_ENABLED (network_config.h). Use the simulator
//  OR real nodes, not both (node IDs would collide).
