/**
 * Represents a contract with defined input and output schemas for event-driven architectures.
 * The ArvoContract class provides type-safe validation and versioning capabilities for event handling,
 * ensuring consistency in message passing between different parts of the system.
 *
 * @example
 * ```typescript
 * const contract = createArvoContract({
 *   uri: '#/my/service/data',
 *   type: 'com.process.data',
 *   description: 'An example contract',
 *   metadata: {
 *     visibility: "public"
 *   }
 *   versions: {
 *     '1.0.0': {
 *       accepts: z.object({ data: z.string() }),
 *       emits: {
 *         'data.processed': z.object({ result: z.string() })
 *       }
 *     },
 *     '2.0.0': {
 *       accepts: z.object({ data: z.number() }),
 *       emits: {
 *         'data.processed': z.object({ result: z.number() })
 *       }
 *     }
