/**
 * Recursively removes a directory and all its contents.
 *
 * This function synchronously deletes the specified directory along with all its subdirectories and files.
 * It first reads the contents of the directory, then iterates over each item. If the item is a directory,
 * it recursively calls itself to delete that subdirectory; if the item is a file, it deletes the file directly.
 * After all contents are removed, it deletes the empty directory.
 *
 * @param dirPath The path to the directory that should be removed.
 * @throws {Error} Throws if the directory does not exist, or if an error occurs during removal.
