/**
 * Overload 1: ApiMethod with positional argument support (supportsArgs = true).
 *
 * Returns a decorator that adds a `fromArgs` function for converting ordered arguments into the input object.
 *
 * @param schema - Validation schema defining expected input structure
 * @param supportsArgs - Must be true for this overload
 * @param keys - Ordered array of input keys (must match schema keys in same order)
 * @returns Decorator that enhances API methods with schema and fromArgs converter
 *
 * @example
 * const decorator = ApiMethod(
 *   { proof: isProof, vk: isVK, publicInputs: isInputs },
 *   true,
 *   ['proof', 'vk', 'publicInputs'] as const
 * );
 *
 * const convert = decorator(async (executor, input) => {
 *   return { result: input.proof };
 * });
 *
 * // Convert positional args to input object
 * const input = convert.fromArgs(proofData, vkData, inputsData);
 * await convert(executor, input);
