gitlab-tracker-notify 0.4.2

//! Desktop notification plugin for gitlab-tracker.
//!
//! Compiled with the `desktop` feature (on by default) to send OS notifications
//! via `notify-rust`. Build with `--no-default-features` for a zero-dependency
//! stub suitable for headless / CI environments.
//!
//! When the user clicks a notification, the MR URL is opened in the default browser.

// ── Internal helper ───────────────────────────────────────────────────────────

/// Show a notification and, if the user clicks it, open `url` in the default browser.
/// The D-Bus action wait is performed in a detached thread to avoid blocking the caller.
