Move a template label

⚠️
Preview — this feature is being built; the design below is the spec.
PUT https://app.syntic.ai/v1/prompts/templates/{template}/labels/{label}

Point a label at a version. Requests using name@label switch on their next call; moving it back is an instant roll-back. Every move is recorded in the audit feed.

For how this fits into a full workflow, see Prompt templates.
