Feature Request

Zed is a code editor that recently added support for language servers in extensions.
I made a draft pull request that added builtin support for typst using typst-lsp before extensions had support for lsps, but I don't have much experience with tree-sitter and scm files, they are mostly ported over from this repository and are incomplete.
There are some builtin extensions with the new lsp support, they are a good reference I think the lsp part is identical, there's an extension guide and there are some helpful doc comments, I'm not sure if the extension should live there with the builtin extensions or here in the editors folder (I'm leaning towards here, but I'm not even sure how it would work with as extensions are added to the index as a git submodule, and submodules cannot only contain a specific folder from a repository...).
Currently zed lacks pdf support, and it's a bit hard to implement due to it also not supporting webviews, I have a rough plan for adding support for it with os pdf apis, but I don't think it's a blocker using typst watch and a browser window is a good stopgap.

Edit: There's also https://codeberg.org/WeetHet/typst.zed/ based on tinymist if anyone is looking for an extension, and I personally have less interest in this issue now
