fix: menubar sub bug and update Melt UI to latest

[huntabyte]

Closes #307
Closes #304

This PR also updates Melt UI to the latest version which results in a multitude of small bug fixes regarding dialogs and menu performance. However, these updates introduce a breaking change to the Slider components.

The Slider.Root now exposes the thumbs and ticks slot props, each of which is an array of builders that must be passed to the Slider.Thumb and Slider.Tick components if being used.

<Slider.Root let:thumbs let:ticks>
	<!-- ... -->
	{#each thumbs as thumb}
		<Slider.Thumb {thumb} />
	{/each}

	{#each ticks as tick}
		<Slider.Tick {tick} />
	{/each}
	<!-- ... -->
</Slider.Root>
