/**
 * Middleware for handling file uploads via multipart/form-data requests.
 *
 * @param options - Configuration options for file uploads.
 * @param options.dest - Destination directory for uploaded files. Defaults to "uploads".
 * @param options.maxFileSize - Maximum allowed file size in bytes. Defaults to 20 MB.
 * @param options.mimeTypes - Allowed MIME types for uploaded files. Defaults to `defaultMimeTypes`.
 *
 * @returns An async middleware function compatible with the UploadContext.
 *
 * @remarks
 * - Parses incoming multipart/form-data requests, saves files to disk, and attaches file metadata to `ctx.files`.
 * - Non-file fields are added to `ctx.body`.
 * - If the request is not multipart/form-data, the middleware passes control to the next handler.
 * - If a file exceeds the maximum size or has a disallowed MIME type, responds with a 400 error.
