Git initialization now explicitly specifies --initial-branch=main to match
GitHub's default branch standard (since October 2020). This prevents the
branch name mismatch that caused features to disappear from the UI when
pushing to GitHub.

- Updated test repository creation functions to utilize environment variables for git author and committer information, preventing modifications to the user's global git configuration.
- This change enhances test isolation and ensures consistent behavior across different environments.
- Added a function to ensure that a git repository has at least one commit before executing worktree commands. This function creates an empty initial commit with a predefined message if the repository is empty.
- Updated the create route handler to call this function, ensuring smooth operation when adding worktrees to repositories without existing commits.
- Introduced integration tests to verify the creation of the initial commit when no commits are present in the repository.
