feat(runes): rewrite SliceSimulator and test component to runes

[ivenuss]

Changes

Rewrites SliceSimulator & PrismicLinkTestWrapper to Svelte 5 runes.

Fixes

Fixes #40 which introduced Svelte 4 syntax which shoudnl't occur in the new codebase as #32 has been already merged.

⚠️ Breaking change

Since <slot /> has been deprecated and it is recommended to use snippets instead.

So this will no longer work:

<SliceSimulator let:slices>
	...
</SliceSimulator>

And you should do:

<SliceSimulator>
	{#snippet children({ slices })}
		...
	{/snippet}
</SliceSimulator>

Note

Medium Risk
Introduces a breaking API change in SliceSimulator (slot → required snippet) that can break consumers at compile-time; runtime logic changes are otherwise localized to UI/event wiring.

Overview
Updates SliceSimulator and PrismicLinkTestWrapper to Svelte 5 runes by switching to $props()/$state() and modern event bindings (onclick/onsubmit/onkeypress) and class handling.

SliceSimulator now renders content via a required children snippet ({@render ...}) instead of <slot {slices} />, changing the public usage from let:slices slot props to snippet-based rendering.

Unnecessary event_directive_deprecated svelte-ignore for new syntax

Low Severity

The event_directive_deprecated svelte-ignore directive was newly added in this PR, but it's unnecessary. This warning only fires when using the old on:click syntax — the code already uses the new onclick/onsubmit/onkeypress attributes (lines 72–74), so the warning will never trigger. The stale ignore directive is misleading and suggests the old syntax is still in use.

And the reason why I noticed this is that we cannot use runes: true in svelte.config, since this legacy Svelte 4 syntax blocks us
