How can I use TypeScript's type system instead of a Zod schema for input validation in next-safe-action?
For example, in the following code, I want to enforce TypeScript type checking in parsedInput without using Zod:

export const uploadFileAction = actionClient.action(
  async ({ parsedInput }: { files : File[]}) => {
    try {
      // Perform file upload

      const { files } = parsedInput;

      const formData = new FormData();
      files.forEach((file) => {
        formData.append('files', file, file.name);
      });

      const resp = await prisma.file.create({
        data: {},
      });
    } catch (e) {}
  }
);

How can I achieve this?
