Overview

Moves a project from the legacy .kamal directory to .dash. Purely local - it never opens an SSH connection and never reads deploy.yml - and only ever runs when the operator asks for it, because silently rewriting someone's working tree is not a deploy tool's job.

Returns [message, color] pairs rather than printing: output belongs to the Thor command, and reaching into the Thor instance for say couples this class to a shell helper whose visibility changes between Thor versions.
