Find is like [Open] except it recursively searches up the directory tree, starting in path.

Open loads a Devbox config from a file or project directory.

ErrNotFound occurs when [Open] or [Find] cannot find a devbox config file after searching a directory (and possibly its parent directories).

Config represents a base devbox.json as well as any included plugins it may have.
