Show labels for running processes #340
Description
When baking a process, we show the process's stdout / stderr outputs, and the PID of the spawned process, and that's about it.
It would be useful to show extra data here too. We should show the file path and line number of the code that created the process recipe automatically. Generally, we have a full stack frame for the recipe already, so it's just a matter of showing it in the TUI.
There's some nuance in how to show the path though. I think, for simplicity, it'd be better to show the path as <project_name>/<file_path>, rather than the full filesystem path. (There's also some nuance if the project has no explicit name set! A good option might be to default to the directory name that contains the project)
