`NogginError`

The error class every engine function throws for usage or state errors. Carries a stable code, a CLI-mirrored exitCode, and a frozen structured data payload. Hosts key user-facing strings off code; message is a short host-neutral fallback.

Thrown by every engine function on usage/state errors.
