Add ANE probe tests and training telemetry for M5 optimization
Four standalone probe tests to characterize the M5 ANE: - test_weight_reload: Can weights be hot-swapped via unload+load without recompilation? - test_perf_stats: Enumerate _ANEPerformanceStats methods/properties and hardware counters - test_qos_sweep: Measure compile/load/eval latency across QoS 0-63 - test_ane_advanced: Probe SharedEvents, weightsBuffer IOSurface, procedureIndex, VirtualClient Training telemetry (train_large.m): - JSON lines to stderr with per-step timing breakdown and per-batch TFLOPS metrics - Enables external monitoring tools to visualize ANE utilization in real-time Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
