v1.2.0

Deploy runs now report builds to the Prisma API: one build per workflow run (idempotent across re-deliveries via the run identity), phase and state updates as the run progresses, the failing step and error on failure, and cancellation from the post step when a run is interrupted. Reporting is best-effort by design: any reporting failure is a workflow warning and never affects the deploy. Requires no workflow changes; runs without a credential keep skipping cleanly.
