Fixes#13390
There's pruning logic in a different place where all unused selectors are commented out. If all selectors are unused, the whole prelude is commented out, resulting in invalid syntax. This is a case that shouldn't happen, therefore simplify the whole "is used" logic to only look at the prelude.
* fix: migrate events to be more inline with svelte 4
* fix: use function instead of action
* chore: generate types
* re-export event modifier substitutes
* chore: replace map with object
* fix: handle nullish values
* fix: use bubbler for delegated events
* chore: generate types
* chore: deprecate legacy stuff
* chore: damn type generations
* fix: implement bubble on props strategy
* chore: revert bubble as prop init but keep fix for restProps
* fix: use `passive` and `nonpassive` actions for `passive` and `nonpassive` modifiers
* chore: i swear i will setup a commit hook for generating types
* chore: update output
* tweak passive/nonpassive types to make them more compact and show up as deprecated
* make terminology more consistent with other places
* eat local, shop local, declare local
* unify name replacement stuff
* remove errant newline
* ensure modifier order is stable and matches svelte 4
* fix
* compute indent once
* joining without newlines seems to work better in common cases
* replace passive/nonpassive handlers in situ
* unused
* simplify
* simplify, remove errant spaces
* only import handlers when necessary
* changeset

This was done previously to align with browser behavior, but the browser behavior actually only makes them passive on window/document/body. Since wheel events are not delegated, we can revert their passive-by-default setting. Closes#13318
For touchstart/touchmove we're not changing it because these events are delegated, which means they happen a lot more often on a target higher up the tree, which may cause jank.
#13225 did not fully fix the described issue: As soon as you have a child component, that child component's anchor will not be in the right ownerDocument yet, and so the logic falls down.
To fix that, we would need to move the ownerDocument check into the microtask - and that map check was mainly done to avoid just that. So instead I opted to simplify the code and just remove the map checks. According to my benchmarking (https://jsbench.me/3hm17l0bxl/1) this has no impact on performance assuming that you'll have cache hits roughly half the time - and even if you'd have much more cache hits, the performance loss is microscopic. Given that the default mode is to not inject styles, this will not be common anyway, so I favor removing that map.
* feat: provide guidance in browser console when logging `$state` objects
Wrap console.log/warn/error statements in DEV mode with a check whether or not they contain state objects. Closes#13123
This is an alternative or enhancement to #13070. Alternative if we deem it the better solution. Enhancement because it's not as robust as a custom formatter: We only check the top level of each entry (though we could maybe traverse a few levels), and if you're logging class instances, snapshot currently stops at the boundaries there and so you don't get snapshotted values for these (arguably this is a more general problem of $inspect and $state.snapshot), whereas with custom formatter it doesn't matter at which level you come across it.
* lint
* use normal warning mechanism, so we can link to docs etc
* add a few more methods
