Add --async-profiler flag to run.py for profiling both Java and native (Rust/C++) code during benchmarks. Unlike JFR, async-profiler captures unified flame graphs across the JVM/native boundary, which is especially useful for Comet workloads. - Add --async-profiler, --async-profiler-dir, --async-profiler-event, and --async-profiler-format CLI flags to run.py - Install async-profiler v3.0 in the Docker image with arch detection - Set ASYNC_PROFILER_HOME in both docker-compose files - Add documentation section in README.md with usage examples - Fix minor bug: skip profiling dir creation during --dry-run
