* [Lit] render DSD attributes based on `shadowRootOptions`
## Changes
- Update `@astrojs/lit`’s `server.js` to properly render elements with `delegatesFocus: false` set in their `shadowRootOptions`.
- Logic is based on `@lit-labs/ssr` [latest implementation as found here](b0c3f82ef0/packages/labs/ssr/src/lib/render-value.ts (L738))
## Testing
A test was added to ensure an element with `delegatesFocus` set to true has this attribute properly included in the rendered static markup.
* chore: add changeset
