fixes#14532
This removes the `reactive_declaration_non_reactive_property` warning altogether. The first version caused many false positives at compile time. The refined runtime version (introduced in #14192) was hoped to fix this, but it turns out we now get loads of false positives at runtime.

Update (some) of the links pointing to the old preview site as mentioned in #13982.
This updates all the links in documentation/ and packages/svelte/messages, but doesn't touch others present in packages/svelte/ or fix the original link in that issue.
* docs: generate pages for compiler/runtime warnings/errors
Ideally each warning has accompanying details so that it doesn't look so empty on the final site, but that can happen separately
* fix
* sort alphabetically, code ticks for headings
* only uppercase first word
* regenerate
* generate codes using [!NOTE], remove any backticks and escape `<` characters
* some prose preceeding the list of compiler warnings
* bring over prose from Svelte 4 a11y warnings
* fix
* lint
* remove backticks from headers, now that they are getting rendered
* Revert "remove backticks from headers, now that they are getting rendered"
This reverts commit c295281848.
* back to normal headers/code blocks
* fix
* separate authored from generated stuff
* newlines

* 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
