DavyThe main window starts hidden and only `window_ready` shows it. macOS suspends animation frames *and* JS timers in a WKWebView whose window has never been shown, so neither the rAF reveal nor its 120ms timer backstop runs and the app becomes an invisible process the user can only kill from Activity Monitor. Add a native watchdog spawned as the last step of setup_app: after 2s it warns and shows the window if it is still hidden. The deadline starts at the end of setup because Tauri serves no IPC until the setup hook returns, and 2s leaves better than 2x headroom over the healthy handshake budget (750ms native-setTheme guard + 120ms reveal backstop plus two local IPC reads), so the flash-free path still wins. ErrorBoundary.componentDidCatch also asks for the reveal. The watchdog covers a render crash too, but the boundary knows at the instant of the crash, so the existing crash panel appears immediately instead of after a blank pause. Deliberately no unconditional on_page_load reveal: `:root` defaults to the dark token set and `data-theme` is only written after settings hydrate, so revealing at load-finished would preempt the theme gate on every launch and flash dark before light for light-theme users. Closes #260
