Introduce a mechanism to automatically pull the latest changes from the git repository when the homepage is accessed. This ensures the application stays up-to-date without manual intervention. The feature includes a lock file (`/tmp/hustoj_git_pull.lock`) to prevent excessive pulls, limiting execution to at most once every 60 seconds. The git pull command runs in the background to avoid blocking the page load, with output logged to `/tmp/hustoj_git_pull.log`.
