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).

Someone could programmatically add a class to an element and Svelte doesn't see it, so having global be part of a modifier is necessary so that Svelte doesn't mark it as unused
fixes#10210
also add event and snippets section to old vs new

- [ ] Run the tests with `pnpm test` and lint the project with `pnpm lint`
* Bump site-kit
* Add content
Our core web vitals have really taken a hit since enabling edge serving. I ran various configs against pagespeed.web.dev and the traditional serverless functions do the best. That's at least partially because I believe serverless functions default to running in us-east-1 where our supabase instance is located. Therefore try going back to Serverless for a while to see the impact.
