## Summary - Add `--async-profiler` flag to `run.py` for profiling both Java and native (Rust/C++) code, with configurable event type (`cpu`, `wall`, `alloc`, `lock`) and output format (`flamegraph`, `jfr`, `collapsed`, `text`) - Install async-profiler v3.0 in the Docker image with automatic architecture detection (x64/aarch64) - Add comprehensive documentation in README.md covering prerequisites, usage examples, and Docker setup - Fix minor bug where profiling output directories were created during `--dry-run` ## Test plan - [x] Verified `--dry-run --async-profiler` produces correct `-agentpath` in `extraJavaOptions` - [x] Verified combined `--jfr --async-profiler` appends both to `extraJavaOptions` correctly - [x] Verified missing `ASYNC_PROFILER_HOME` produces clear error message - [ ] Run benchmark with `--async-profiler` on a Linux host to validate end-to-end profiling 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
