// bindTrayClick wires the tray icon's left-click handler on Linux.
//
// Both Linux click paths converge on Wails' linuxSystemTray.Activate, which
// fires the registered clickHandler:
// - Real SNI hosts (KDE Plasma, Waybar, GNOME Shell + AppIndicator) invoke
// org.kde.StatusNotifierItem.Activate over D-Bus on left-click.
// - The in-process StatusNotifierWatcher + XEmbed host used on minimal WMs
// (Fluxbox, i3, dwm, OpenBox) maps a Button1 press to that same Activate
// call itself (xembed_host_linux.go), so it routes through the same hook.
// Registering OnClick here therefore covers both paths with one handler — no
// changes to the watcher or XEmbed C code are needed. Left-click now opens the
// main window; right-click still opens the menu via Wails' default
// SecondaryActivate→OpenMenu handler (and the XEmbed GTK popup on minimal WMs).
// Expected behaviour per tray host:
//
// Host Left click Right click
// KDE Plasma, Waybar main window (Activate) menu (host-rendered)
// GNOME Shell + AppIndicator menu only menu only
// Minimal WMs via XEmbed host main window (Activate) XEmbed GTK popup
//
// OnClick fires only on org.kde.StatusNotifierItem.Activate — a real left
// click. KDE/Waybar send it over D-Bus; the in-process XEmbed host
// (xembed_host_linux.go) maps a Button1 press to the same Activate call.
//
// GNOME Shell + AppIndicator never sends Activate: it renders the dbusmenu
// on ANY click and only reports the menu opening via dbusmenu
// Event("opened"). Upstream Wails treated that event as a click, so on GNOME
// both buttons raised the main window on top of the menu, and on KDE/Waybar
// a right click raised it over the freshly opened menu. The netbirdio/wails
// fork (go.mod replace) drops that heuristic: a menu open never fires
// OnClick. On GNOME the main window is reached via the "Open NetBird" menu
// entry; left-click-opens-window is not achievable there anyway, since the
// host always opens the menu itself.
//
// We do NOT register OnDoubleClick: Wails' Linux SNI backend never fires it
// (unlike Windows). And we deliberately skip AttachWindow — it plus Wails3's
