* breaking: apply fallback value every time in runes mode
closes#9948
* apply fallback value in setter
* encapsulate fallback logic
* we should keep this logic out of b.set, since it's very specific to accessors

pre effects, which also contain `$:` statements, are more controlled in legacy mode and should only run once per tick, in their defined order. Flushing them out of order can result in bugs. Related to #10795 and #10787
* fix: improve element class attribute behaviour
* Update packages/svelte/src/internal/client/dom/elements/class.js

The await block scope analysis was flawed because it did not set the scope for the value/error field before visiting those nodes, resulting in the wrong scopes getting references
As a byproduct, this fixes#8141
* follow up to 10846
* lint
* simplify
* don't update value
* rework logic, rely more on mutation observer, fix bug related to select multiple
* fix lazy select options bug

- the `component` parameter expects a component constructor type, not an instance type
- use `import('svelte')` instead of relative paths to not inline all types that are already present in the sibiling module declaration
* null out teardown function
* add managed effects to effect tree
* let the code breathe a bit
* bit more
* man, that's better
* create correct parent-child relationship between if block and its branches
* remove unnecessary arg
* each blocks already have the correct parent-child relationship so i guess we can get rid of this
* simplify
* unused import

* fix: invalidate store when mutated inside each block
fixes#10771
* Update packages/svelte/src/compiler/phases/3-transform/client/visitors/template.js
We can simplify pre effects by not doing the flush logic at all now. Instead we can move the flushing logic to the only place its needed – for beforeUpdate
* feat: add reactive Set class to svelte/reactivity
* add some type safety
* simplify, read entries lazily
* failing unit test
* fix deletions
* minor tweaks
* work around effect ordering bug
* simplify, make entries lazy
* small tweak
* use var, minor tweaks
