[FEATURE REQ] Add command to (re)generate/update .env file

[Clockwork-Muse]

Description.

When cloning a repository that includes an existing project, (by default) no .env file is included, making it difficult for other users to get started with project.

It would be beneficial to have a command that would create the .env file, or be able to update it (eg, update runtime/schema versions to current).
