TypeScript interface-like schema validation system that's easier to use than Zod

    // 🔥 Exclusive conditions - only specific roles get these fields
    permissions: "when:role=admin:string[]",                    // Only admins
    maxProjects: "when:accountType=free:int(1,3):int(1,)",      // Free users limited, others unlimited
    paymentMethod: "when:accountType!=free:string",             // Premium/Enterprise only

    // Basic fields
    name: "string",
