add projects/ - standalone scripts alongside the Docker stacks

Two real, working scripts: an Ansible playbook run-menu (the same
pattern used identically across both the fleet-config and infra-
provisioning repos), and cuesplit, a frame-accurate FLAC/.cue
splitting utility. Sanitized paths only, logic untouched.

README gets a new "Scripts & Tooling" section pointing at it, placed
right after "What's Running" alongside the other repo-structure
pointer.
