tinty 0.33.0

//! General CLI integration tests not specific to a single subcommand.
//!
//! Covers: no-arguments help output, tilde (`~`) expansion for `--config`
//! and `--data-dir` paths, and default XDG data directory behaviour.
//!
//! Requires network access on first run (repos are cached in `tmp/repos/`).
