Support package.json: scripts, package manager, runtimes, dependencies, devEngines

The most time-saving thing is to have a auto-complete on package versions in dependencies etc.

Also, would be pretty handy to quickly run scripts in a built-in terminal via project runtime (depending on a lock file, or engines/devEngines ), update package versions via specified package manager (NPM, Bun, PNPM, Deno etc) and package registry. Also, workspaces support for auto-complete in the imports.

I've seen Package Version Server (https://github.com/zed-industries/package-version-server), but it is pretty basic and only shows info about current version.

P.S. I did use Zed much yet, sorry if I missed something that already works. But when Git UI is released I wanna give it another try, looks pretty good now!
