Minor release. Overridable navigation-landmark and heading-level semantics, screen-reader-announced form errors, and an engine-neutral rich-text-editor factory — all backward-compatible.

Added

<x-wirekit::sidebar> gains a label prop for the navigation landmark's accessible name. It defaults to "Sidebar"; override it — or pass aria-label / aria-labeledby directly — when a page has more than one navigation landmark, so assistive technology can tell them apart. No duplicate or conflicting name is emitted.
<x-wirekit::empty-state> gains a level prop for the title's heading level. Choose 1–6 (default 3) to fit the surrounding document outline so screen-reader heading navigation stays correct. The default still renders an <h3>.
<x-wirekit::field> and <x-wirekit::input> announce validation errors to screen readers. The error message now renders as a polite ARIA live region by default, so an error that appears dynamically — for example after a Livewire round-trip — is announced without the focus having to return to the field. Opt out with announceError="false" when your page runs its own live region.

Changed

The <x-wirekit::editor> rich-text component now uses an engine-neutral window.wirekitEditor(config) factory. The previous window.tiptapEditor name keeps working as a deprecated alias, so upgrading is a one-line rename in your editor bootstrap.
