v0.12.1

Added

• Native toasts. <%= native_toast_tag flash[:notice] %> in your layout floats confirmations over all app chrome, including the nav bar, and navigating back never repeats one. Both platforms, both modes. Docs, including the Inertia components.
• RubyNative.toast("Saved.") shows a toast from client-side JavaScript, no server round trip. A browser ignores the call, so it is safe to run unconditionally.

Fixed

• ruby_native preview now names the real reason your app did not serve its config. Every failure used to blame an unmounted gem and link a docs page that does not exist, so a 500 from a pending migration sent you to re-check a mount that was already fine. A 500 now points at your app, and a redirect names where the request went.
