PulsarKey v1.4.0: Cross-Platform macOS Support & Streamlined Experience

🌌 PulsarKey v1.4.0 Release Notes

🍎 Cross-Platform macOS Support (Single Rust Codebase)

• Unified Rust Core: Full compatibility with Pop!_OS Linux and macOS (Darwin 12+).
• macOS PAM Integration: Directly targets /etc/pam.d/screensaver, /etc/pam.d/authorization, and /etc/pam.d/sudo.
• Presence Sentinel Daemon: Monitors USB insertion and removal via IOUSB / ioreg, locking the display immediately when the token is unplugged.
• Metal Acceleration: The Iced GUI Settings window natively renders via Apple Metal on macOS and Wayland/Vulkan on Linux.
• Packaging Suite: Adds macOS App Bundle (PulsarKey.app), DMG/PKG generation scripts (build_mac.sh), and a Homebrew Cask formula (pulsarkey.rb).

⚙️ Integrated Settings View as User Selection

• Running pulsarkey in a terminal now presents an interactive view selector to launch the Settings GUI [2] or view the Terminal Status Dashboard [1].
• Direct shortcut: pulsarkey -g (or pulsarkey gui).
• Automatically launches the Settings GUI when double-clicked or invoked from desktop application menus.

📖 Streamlined Documentation

• Comprehensive 2-minute quick start guide.
• Plain-English instructions for everyday lockscreen unlocking and passwordless elevation.
