opensnitch-zenity: a lightweight prompt-only UI (single Go binary, works on Wayland)

[vmartinv]

I wrote a small alternative UI for opensnitchd that only answers connection prompts, using zenity dialogs: https://github.com/vmartinv/opensnitch-zenity

• I wrote it because opensnitch-ui (PyQt) sits at ~130 MB RSS all the time just to wait for prompts; this is a single static Go binary at ~20 MB RSS that talks to the daemon over the same gRPC socket.
• Allow/deny once or always. "Always" offers program+host, program, or host rules, which the daemon saves as usual. "Copy details" copies the connection info to the clipboard.
• No stats, rule editor or tray: rules are edited as JSON in /etc/opensnitchd/rules/.
• Written for tiling and Wayland setups (tested on Hyprland with opensnitchd 1.7.2), where the PyQt pop-up issues on Wayland can be a problem.
• Install from the AUR (yay -S opensnitch-zenity), Nix (nix run github:vmartinv/opensnitch-zenity), or static release binaries.

It's unofficial and not meant to replace opensnitch-ui for people who want the full GUI. Feedback is welcome, especially on whether the rules it creates match what the stock UI would send.
