Benchmark datasets are downloaded artifacts, not source files. Store them under $XDG_CACHE_HOME/colibri/bench (~/.cache/colibri/bench) on Linux/macOS and %LOCALAPPDATA%\colibri\bench on Windows instead of polluting the source tree at c/bench/. fetch_benchmarks.py already calls os.makedirs(out, exist_ok=True), so the new cache path is created on first use.
