Added

• Exported SuperValidateOptions type.
• Exported MergeUnion, MergeFormUnion and a mergeFormUnion utility, for handling discriminated unions in forms.

Fixed

• Fixed diff algorithm problem with tainted objects.
• Prevented crash when custom validity doesn't exist for an element.
• dateProxy didn't restore properly with snapshots.
• Fixed JSON Schema for simple adapters with empty arrays.

Changed

• Bumped TypeBox peerDep requirement to 0.34.28.
• Bumped Effect peerDep requirement to 3.13.7.
• Bumped Valibot peerDep requirement to 1.0.0-rc.3.
• Bumped Zod peerDep requirement to 3.24.2.

Deprecated

• The flashMessage option is now deprecated, since SvelteKit has moved to $app/state instead of $app/stores, making it hard to support both. Use sveltekit-flash-message directly (setFlash or redirect) instead of integrating it with Superforms, it's less complicated as well.
