No headless Tracy capture tool was found.
Validated fallback:
  1. Build benchmarks with Tracy enabled when available:
     meson setup --reconfigure build/release -Denable-profiling=true
  2. Start the GUI profiler in another terminal:
     tracy-profiler
  3. Run the benchmark wrapper:
     scripts/run_tracy_benchmark.sh write_coordinator_bench

For fully programmatic capture, install/build Tracy's capture tool and run:
  YAMS_TRACY_CAPTURE_CMD=/path/to/capture \
  YAMS_TRACY_CAPTURE_ARGS='<version-specific output args>' \
  scripts/run_tracy_benchmark.sh write_coordinator_bench
