Fix macOS window lifecycle: close now hides reliably and tray hide no longer reopens

[Copilot]

The companion app’s main window lifecycle on macOS was inconsistent: clicking the window close control did not properly dismiss the app window, and selecting Hide from the tray menu could immediately re-show it. This updates window/tray event handling to make hide behavior deterministic.

• Window close handling (macOS-visible behavior)

  • Added a CloseRequested handler for the main window.
  • Close now prevents default teardown and hides the window instead, matching tray-style background behavior.

• Tray interaction behavior

  • Removed unconditional tray icon event handling that forced the main window to show on tray events.
  • This prevents the hide action from being immediately negated by an auto-show path.

• Scope intentionally limited

  • No menu bar asset or app icon asset changes were included in this PR (handled separately as requested).

.on_window_event(|window, event| {
    if window.label() == "main" {
        if let WindowEvent::CloseRequested { api, .. } = event {
            api.prevent_close();
            let _ = window.hide();
        }
    }
})

• Fixes [Bug]: App close button doesn't work on macOS and various issues #8

Pull request overview

This PR adjusts the Tauri companion app’s window/tray event handling so the main window can be reliably dismissed on macOS (close hides the window instead of tearing down) and tray “Hide” no longer triggers an immediate re-show.

Changes:

• Added a WindowEvent::CloseRequested handler for the main window to prevent close and hide the window.
• Removed unconditional tray icon event handling that always showed the main window, avoiding auto-reopen after hide.
