//! Embedded .app bundle for native macOS notifications.
//!
//! The Swift notification helper (`notify.swift` compiled to `email-cli-notify`)
//! must run from a codesigned `.app` bundle for `UNUserNotificationCenter` to
//! work on macOS 26+. Release tarballs and `cargo install` ship only the main
//! binary, so we embed the bundle here and extract it to the user's data dir
//! on first daemon launch (or when the user runs `email-cli daemon install-helper`).
