Add @effect/language-service (#4159)

See
[`@effect/language-service`](https://github.com/Effect-TS/language-service/tree/main).

To get a feeling for the utility of this:
```sh
git clone https://github.com/Effect-TS/language-service
cd language-service
pnpm i
pnpm build
# ensure lsp server is using workspace tssdk
# open ./examples/**/*
```

**NOTE:** This only enhances LSP experience and does not contribute to
static checks.
