Key updates include:
1. **Image Information Retrieval:**
 * `get_tags_data`: Asynchronously retrieves the latest n tags for a specified image from the Docker Hub API (`/v2/repositories/.../tags/`).
 * `parse_dockerhub_url`: Parses Docker Hub page URLs to extract namespace and repository names.
2. **Docker Operation Encapsulation:**
 * `pull_image`: Executes `docker pull`.
 * `tag_image`: Executes `docker tag` to mark the image for the target private repository.
 * `docker_login`: Executes `docker login`, using credentials obtained from environment variables to log in to the target repository.
 * `push_image`: Executes `docker push`.
3. **Backup Recording:**
 * `is_image_backed_up`: Checks if the image is already in the record file.
 * `record_backup`: Writes the successfully backed-up image version to the record file.
4. **Main Logic (`main` function):**
 * Loads the target repository URL, namespace, and authentication credentials via environment variables.
 * Configures the number of tags to retrieve, the record file path, and the list of image URLs to process via command-line arguments.
 * Coordinates the entire flow: login -> get tags -> (check record -> pull -> tag -> push -> update record).
 * Uses `aiohttp` for asynchronous API requests.
5. **Logging and Error Handling:**
 * Comprehensive use of the `logging` module instead of `print` to provide structured log output.
 * Error capturing and handling for Docker command execution, API requests, and file operations.
6. **Documentation:**
 * Updated `README.md` with detailed instructions on script configuration (environment variables, command-line arguments), dependency installation, and execution methods.
This script can now automatically pull multiple versions of specified images from Docker Hub based on your configuration, push them to a configured private repository (such as Tencent Cloud or Alibaba Cloud), and locally record backed-up images to avoid redundant operations.

I've added a new GitHub Actions Workflow (`.github/workflows/daily_image_backup.yml`) that will automatically run the `main.py` script every day.
Key features:
- Scheduled to run daily at 02:00 UTC.
- You can also trigger it manually.
- The target repository URL, namespace, and authentication details are securely configured using GitHub Actions Secrets.
- The Workflow steps include checking out the code, setting up the Python environment, installing dependencies, and running the `main.py` script.
I've also updated the `README.md` file with instructions on how to configure and use this new Workflow, including the required GitHub Secrets.

Translate the usage instructions for the `main.py` command-line script and the `daily_image_backup.yml` GitHub Actions workflow into Chinese to improve readability for Chinese users.
