Closes#13493.
This PR allows the usage of getContext() inside $derived runes. Previously, you could use it, but only on init and not updates – and this inconsistency was unnecessary. We can make it work just like we do in other places.
I resisted this previously because it felt a bit wasteful, but I now think that there's really no way around this: Instead of only going upwards the tree while matching, for `:has` we go _down_ the tree to see what matches. More specifically, we're collecting the children of the current element and then check if one of those does match the selectors inside `:has`.
This makes the way the code works easier to reason about and also removes some boolean tracking we had to add for the previous approach.
Fixes#13779
Fixes#13717
There are two parts to this:
1. the parent selectors weren't passed along for the check inside `:has`, which in case of a leading combinator would mean it would always count as unused
2. In case if a selector like `x > y:has(z)`, the prior logic would correctly determine that for element `z` there's a match for the `:has` selector, by first checking its contents and then walking up the tree. But after it did that, it would try to walk up the tree once more, which is a) wasteful b) buggy because the tree walking mechanism would no longer be adjusted for the `:has` special case, resulting in false negatives. To fix that, the `:has` will return a new value from the function, signaling that it already fully checked the upper selectors, and so the function calling it will skip doing that.
- detect store mutations and not use `$derived` in that case, fixes#13723
- better detect `let x` that can be folded into `$derived`, fixes#13727

The other part of #13395
This implements scoping for selectors inside `:not(...)`. The approach is almot the same as for `:is/where(...)`.
This is a breaking change because people could've used `:not(.unknown)` with `.unknown` not appearing in the HTML, and so they need to do `:not(:global(.unknown))` instead.
While implementing it I also discovered a few bugs, which are fixed in this PR:
- `foo :is(bar baz)` wasn't properly handled. This selector can mean `foo bar baz` but it can also mean `bar foo baz` (super weird, but it is what it is). Since our current algorithm isn't suited for handling this, we just assume it matches and scope it. Worst case is we missed a prune
- `bar` in `:global(foo):is(bar)` was always marked as unused, even if it matched
The main part of #13395
This implements scoping for selectors inside `:has(...)`. The approach is to first descend into the contents of a `:has(...)` selector, then in case of a match, try to match the rest of the selector ignoring the `:has(...)` part. In other words, `.x:has(y)` is essentially treated as `x y` with `y` being matched first, then walking up the selector chain taking into account combinators.
This is a breaking change because people could've used `:has(.unknown)` with `.unknown` not appearing in the HTML, and so they need to do `:has(:global(.unknown))` instead

- make sure to not overfire before/afterUpdate
- make sure to not fire mutable sources when they were mutated
- only show deprecation warning when in runes mode to not clutter up console (this is in line with how we made it in other places)
