Feature Request: Multiple terminals in parallel

Disclaimer upfront: This is a bit of a moonshot, but hear me out 😄.

Current situation

In devbox.json, I can configure a shell.init_hook array:

{
  "shell": {
    "init_hook": ["echo 'One'", "echo 'Two'"]
  }
}

These commands run in sequence and each has to terminate.

Future

In most of my projects, I need to spin up a few services in parallel. For example:

• A database
• An API server
• A web app

Each runs in its own terminal and prints its logs to the corresponding terminal tab/window.

It'd be great if shell init_hook commands ran in their own terminal and could be non-terminating. With that, anyone could open a devbox shell and have all necessary services up and running. All they have to do is write code. You could even fire up a test suite in watch-mode in one of the terminals and have instant feedback whether you're breaking tests as you develop code.
