* fix: add pointer and touch events to a11y_no_static_element_interactions warning
Fixes#17527
The a11y_no_static_element_interactions warning now triggers for pointer
and touch events (onpointerdown, onpointerenter, ontouchstart, etc.)
in addition to mouse and drag events.
This ensures accessibility warnings are consistent across all pointer
input methods.
* fix test

PR #17461 added the `wait` function to `reactivity/async.js` and modified the compiler to generate `$.wait()` calls, but forgot to export it from `index.js`.
This causes a runtime error when using `await` inside `$derived()` with `experimental.async: true`:
```
TypeError: $.wait is not a function
```
Fixes#17529

In #17105 one line in `update_reaction` was changed that can cause reactivity loss. It checks if the reaction is updated inside of an effect and only then will push to the reactions. The prior version had an additional check to still add to the reactions if there is already at least one reaction on the derived, indicating it is connected. Removing this check fixes#17263 while keeping correctness: a connected derived by definition at least has one reaction and therefore can properly cleanup.
* chore: more effect helpers
This adds two new helpers that helped me tremendously with getting to the bottom of #17197:
- `log_reactions`: Logs the graph of reactions starting from the given signal, and also checks if the effect leafs are reachable and if they are able to schedule a root
- `log_inconsistent_branches`: Logs if there are paths in the graph where a branch is clean above a non-clean branch, which means that the part of the graph cannot schedule batches anymore
* shut up eslint
* fix: link offscreen items and last effect in each block correctly
It's possible that due to how new elements are inserted into the array that `effect.last` is wrong. We need to ensure it is really the last item to keep items properly connected to the graph. In addition we link offscreen items after all onscreen items, to ensure they don't have wrong pointers.
