MAX changelog updates:

  • kbench now runs benchmarks via shared library (.so) by default, reusing
    persistent workers and CUDA contexts instead of spawning subprocesses.
    Benchmark execution phase is ~10x faster (e.g. 4.25 h → 0.4 h on a tuning
    workload). Falls back to subprocess mode when profiling or using custom exec
    wrappers.
