//! Version banner output.
//!
//! `print_full` matches curl's `--version` format so existing curl tooling
//! (e.g. `grep -q HTTP2 <(curl --version)`) works against recon output.
//! `print_short` prints just `recon <version>` for scripts that only want
//! the number.

// Update these when the corresponding Cargo.toml entries change majors/minors.
// Patch-version drift is not reflected — the banner reports the API surface.

/// Protocols recon can speak. Keep this list in sync with the URL-scheme
/// dispatch in `main.rs` (and the `source::resolve_file_url` branch for
/// `file://`). When adding or removing protocol support, update this list
/// so `recon --version | grep <proto>` stays accurate. Rendered sorted
/// case-insensitively in `print_full`.
