* fix: allow nested `<dt>`/`<dd>` elements if they are within a `<dl>` element
This introduces a resets array, which means descendants that are forbidden are allowed again, if an element within the resets array is encountered between the tag and the forbidden descendant

* chore: perf tweaks for actions/styles/classes
- check if we really need to add/remove the class (calling `includes` first is cheaper than always setting/removing it)
- check if we really need to update a style (calling `getPropertyValue/setProperty` is expensive)
- check if we should call the action's update function (this is not only a perf tweak but also a correctness fix)

* feat: make `<svelte:component>` unnecessary in runes mode
In Svelte 4, writing `<Component />` meant that the component instance is static. If you made the variable `Component` a reactive state variable and updated the component value, the component would not be reinstantiated with the new value - you had to use `<svelte:component>` for that. One reason was that having a dynamic component was more overhead, which is no longer the case in Svelte 5. We can therefore reduce the potential API surface area (by maybe deprecating `<svelte:component>` in the future) by allowing Svelte to recognize when a component variable is potentially dynamic. It turned out that this was already mostly the case. This PR fixes one case where it wasn't, and fixes another where this was wrongfully applied in legacy mode.

language tools has to type its own shape for backwards compatibility, and it currently doesn't include the `$on` and `$set` methods, which means without widening the type as done here you would get a "this shape is not accepted" type error when passing it to `ComponentProps`
