//! Reproducible harness for benchmarking clipboard attachment reads
//! (the paste hot path).
//!
//! Runs one `get_attachments()` — the same unified probe the pager's paste
//! pipeline executes — and prints the outcome plus wall time. Benchmark the
//! native in-process read against the `osascript` fallback with hyperfine:
//!
//! ```text
//! # put an image on the pasteboard first, e.g.:
//! #   osascript -e 'set the clipboard to (read (POSIX file "shot.png") as «class PNGf»)'
//! cargo build --release -p xai-grok-shared --example clipboard_probe
//! hyperfine --warmup 2 \
//!   -n native './target/release/examples/clipboard_probe' \
//!   -n osascript 'GROK_CLIPBOARD_NO_NATIVE_READ=1 ./target/release/examples/clipboard_probe'
//! ```
//!
//! Exits non-zero when the read errors so hyperfine aborts loudly instead of
//! averaging failures.
