Automate Copying of English Assignments to Separate Repository

## Description:

This issue proposes automating the process of copying modified English-language assignments from the main (bilingual) repository to a dedicated English-only repository. This will streamline maintenance and ensure consistency between the two repositories. The initial concept for this automation was developed with the assistance of an AI language model.

## Goals:

* Reduce manual effort in maintaining separate repositories.
* Ensure the English-only repository is always up-to-date.
* Improve accessibility for international students.

## Proposed Implementation:

1. Repository Setup:

* Create a separate repository for English-only assignments.
* Set up access credentials (e.g., SSH keys, deploy keys) to allow automated pushes to the English-only repository.

1. Automation Script:

* Write a Python script (copy_english_assignments.py) that performs the following:
* Detects changes in English assignment files in the main repository.
* Copies modified English files to the corresponding location in the English-only repository.
* Commits and pushes the changes to the English-only repository.

1. Git Hook Integration:

* Create a `post-commit` Git hook in the main repository that triggers the Python script after each commit.

## Action Items:

* [ ] Create English-only assignment repository.
* [ ] Set up access credentials for the English-only repository.
* [ ] Write `copy_english_assignments.py` script.
* [ ] Change detection logic (e.g., `git diff`, optional language check)
* [ ] File copying logic (`shutil.copy`)
* [ ] Commit and push logic (if applicable)
* [ ] Error handling and logging
* [ ] Implement `post-commit` Git hook.
* [ ] Test the hook thoroughly in different scenarios (file modifications, deletions, new files).
* [ ] Handle potential conflicts if both English and Korean versions are modified in the same commit.
* [ ] Add error handling and logging to the script.
* [ ] Test the entire workflow thoroughly to ensure seamless operation.
* [ ] Document the setup and usage of the hook in the README.

## Additional Considerations:

* Investigate potential alternatives to Git hooks, such as GitHub Actions, for automation.
* Explore more advanced language detection techniques if basic filtering is not sufficient.
* Implement a mechanism to resolve conflicts if both English and Korean versions of a file are modified simultaneously.
