Why
No more VM plumbing every time you start a lab.
Yeast handles the boring pieces: project config, image cache, qcow2 disks, cloud-init seed files, QEMU startup, SSH readiness, state, status, stop, and cleanup. The first release is small on purpose: prove the lifecycle before adding provisioning, snapshots, private networks, LabsBackery, MCP, and cloud workers.

For labs
Small core now. Lab engine later.
v0.1 proves lifecycle. Next comes Caddy provisioning, snapshots, and multi-VM labs.
For tools
Pretty output, clean JSON.
Humans get readable CLI output. Automation gets structured results.
