v2.12.6

Fixed

• The Zod adapter didn't handle reused schemas ($ref) properly.
• The "GET to POST" modification for use:enhance was only intended for SPA mode to fully support progressive enhancement, so it now properly checks for that before adding the missing method="POST" attribute on the form.
• The tainted message didn't trigger on page refresh or closing a tab in the browser.
• FormPathLeaves caused a memory leak when using svelte-package.
