* fix: remove readonly validation
The readonly dev time validation results in false-negative object equality checks: The original object is proxified and thus comparisons could be between the unproxified and proxified version, which will always return false. Fixes#10372
There's also the problem that an object could be passed into a component but then passed upwards into shared state. At that point, it should no longer be readonly, but it's not possible to statically analyze these points. Fixes#10372
Lastly, the each block logic mutates an internal array and that also throws errors with the readonly logic. Fixes#10037

Adjusts the escaping mechanism done for server compilation. For template literals it's now only applied when explicitly told, which is the case for generated literals from the html template. Fixes a bug where a template literal string inside the `@html` tag was wrongfully escaped (https://github.com/sveltejs/svelte/issues/10359#issuecomment-1949678228)
In Svelte 4, scripts inside `@html` were not executed when it was created client-side. This is because `innerHTML = ..` which was used under the hood does not execute scripts due to security reasons. This adjusts the code so the same is true for Svelte 5.
Ensure update methods of actions and reactive statements work with fine-grained `$state` by deep-reading them. This is necessary because mutations to `$state` objects don't notify listeners to only the object as a whole, it only notifies the listeners of the property that changed.

Return `pop` directly by returning the component from it; gets rid of extraneous variable declaration

Add source map merging for preprocessors and get tests passing.
- fixed some issues around the `sources` array where they weren't calculated relative to the input correctly
- adjusted some CSS tests because due to our own CSS parser the AST is less granular, so there are less mappings now. Don't think this is a problem, but worth thinking about
- removed enableSourcemap but only log a warning, the reason this was introduced was to mitigate a bug in Vite which occured when having the source map inlined into the SSR'd output. Since SSR doesn't contain inlined CSS anymore (and if it did, we would omit the source map) the reason for which it was introduced no longer exists
- files without js mapping in it have no source mappings yet (originally added in Svelte 4 for #6092)
* rename $derived.call to $derived.by
* more replacements, plus a compiler error
* regenerate types

Relax the runtime error to only throw when you're passing a binding with an undefined value. This makes it possible to provide components in a way that can be used more flexibly while keeping the error to guard against the case that we want to avoid: a default value propagation up.
* fix: handle sole empty expression tags
When there's only a single expression tag and its value evaluates to the empty string, special handling is needed to create and insert a text node
fixes#10426
* fix
* need this, too
* Update packages/svelte/src/internal/client/operations.js

Closes#9420.
This PR creates an $effect.pre (before beforeUpdate and an $effect (for afterUpdate) and, inside those, listen for all locally declared signals plus reactive props. This does mean that we need to link the locally declared signals to the component context (the reverse of the current behaviour, wherein we link the component context to locally declared signals).
fixes#10296
Also make sure to use the server export conditions when resolving Svelte imports from inside the server compiler output
