* feat: add parent hierarchy to `__svelte_meta` objects at dev time
This adds a `parent` property to the `__svelte_meta` properties that are added to elements at dev time. This property represents the closest non-element parent the element is related to. For example for `{#if ...}<div>foo</div>{/if}` the `parent` of the div would be the line/column of the if block.
The parent is recursive and goes upwards (through component boundaries) until the root component is reached, which has no parent.

an unowned derived should still add itself as a reaction while it is properly connected, which means it can be cleaned up correctly - and this connection is indicated by it having reactions.

* fix: ensure sources within nested effects still register correctly
When an effect creates another effect and a proxy property is read that wasn't before, the proxy will have logic where it creates the new signal in its original reaction context. But it did not have logic to correctly handle the `reaction_sources` array which prevents effects/deriveds rerunning when state created inside themselves is read and then changed inside them: Since `reaction_sources` wasn't take the reaction context into account, false positives could occur where nested effects would not register the sources as dependencies.
Fixes#15870
* oops forgot to push this
Make sure we track statically visible dependencies and untrack indirect dependencies
Fixes#14351

Closes#16164
We can't set everywhere within with_parent otherwise if it's the first time we are reading a derived it could look like we are setting state in a derived (which you are not).
