TypeScript Language Server in clickhouse-js

typescript-language-server is declared as a root devDependency, so after npm install (see the setup skill) it is available via npx and uses the workspace-local typescript (6.x) compiler, matching CI exactly.

The server (6.x) requires Node.js >= 22.22.2, newer than the repository's Node 20 minimum; on Node 20 npm install only warns, but the server isn't supported there.

Starting the server

From the repo root:

npx typescript-language-server --stdio
