Validate a bundle

The real compile gate. Code workflows are type-checked server-side against the real @general-input/core; apps get the design-system lint and handler references; agent workflows get the agent.json schema and a non-empty instructions.md.

      "message": "Property 'foo' does not exist on type 'WorkflowContext'."
    },
    { "message": "Credential slot 'slack' is not wired." }
