/**
 * Creates a forward-compatible Zod schema for enums that normalizes unknown values.
 *
 * When registry is updated with new enum values, older SDK versions will parse
 * the unknown value as the specified `unknownValue` instead of failing entirely.
 *
 * This enables:
 * - Old SDK + New Registry: Works - unknown values become `Unknown` variant
 * - New SDK + Old Registry: Works - known values parse normally
 * - TypeScript exhaustiveness checking forces explicit handling of unknown cases
 *
 * @param enumObj - The enum or const object to validate against
 * @param unknownValue - The value to use for unknown/new enum variants
 * @returns A Zod schema that accepts any string but normalizes unknown values
 *
 * @example
 * ```ts
 * const zProtocolType = forwardCompatibleEnum(ProtocolType, ProtocolType.Unknown);
 * zProtocolType.parse('ethereum'); // => ProtocolType.Ethereum
 * zProtocolType.parse('newprotocol'); // => ProtocolType.Unknown
 * ```
