tsunagi/crates/tsunagi-tray/src/main.rs

//! Tray application for managing a running tsunagi agent.
//!
//! A small window (networks, their peers and addresses, join/leave, per-network
//! active and broadcast switches) plus a tray menu (Open, Quit). It is a thin
//! client over the agent's local control socket — the same interface the CLI
//! uses — and owns its own runtime, logger and event loop, like the CLI binary.

// The window is created hidden-to-tray on close rather than exiting; the binary
// itself may exit on Quit. Nothing here is a library.
