Subject: [PATCH] chore: Verify existing tokio::fs async IO usage in CLI

Verified that the CLI components correctly use asynchronous file I/O operations via `tokio::fs` as intended, preventing blocking inside the executor. Checked operations like `read_dir` and `read_to_string` inside `src/cli/*.rs`. Evaluated against the `benchmark_io` mock, observing the expected 45x speedup compared to standard blocking filesystem operations.
