fix(linux): release the GTK window and webview objects on close - #3

windowNew sinks a reference into every GtkApplicationWindow it creates, but close() only called gtk_window_destroy, which unmaps the window and dissolves the widget tree without freeing it. The sunk reference kept the refcount above zero, so dispose never ran, the child WebKitWebView stayed alive, and its WebKitWebProcess was never reaped. Every window opened over a session left one behind: on a tray application that outlives its windows the residents accumulated at roughly 100MB each, reaching 662MB of resident process tree after four open/close cycles where a clean run settles at 238MB. The reference windowNewWebview takes on the WebKitSettings and the WebKitUserContentManager leaked the same way. The web view holds its own reference to both, so hand ours back once it has them. unregisterWindow now runs before the unref because it only uses the pointer as a map key, and touching it afterwards would be a use-after-free.
