A11y warning: Avoid using autofocus

[j-hannes]

When running the application, a warning appears in the console:

rollup v1.7.3
bundles src/main.js → public/bundle.js...
(!) svelte plugin: A11y: Avoid using autofocus
src/TodoMVC.svelte
92:     on:keydown={createNew}
93:     placeholder="What needs to be done?"
94:     autofocus
        ^

Seems there is some argument over it, sveltejs/svelte#6629, because it is not browser-native (it is handled by Svelte explicitly calling focus). The solutions are server-side rendering and letting the browser handle it, or else carefully customizing behavior based on device characteristics like in huggingface/chat-ui#183. But mostly, it should just be disabled by adding <!-- svelte-ignore a11y-autofocus -->
