Cmd/Ctrl+S used to snapshot silently. A new app-wide ToastProvider
(components/Toast.tsx) owns a bottom-center stack — permanent polite
live region, auto-dismiss after 2.5 s, click to dismiss early, error
variant. Both snapshot paths (the keyboard chords in PageEditorPage and
the save-version TopBar button) now confirm with the version name when
there is one, and their failure alert becomes an error toast.
The plugin host capability ui.toast (declared since #74, wired
nowhere) connects to the same stack: PluginBlockScope carries the
showToast handle, plugin-block passes it into the sandbox context.
