This pull request hardens git repository initialization against argument and option injection by verifying that the initial branch name does not start with a hyphen (-). Corresponding unit tests are added in git.test.ts to ensure this behavior.

We check if the initialBranch parameter starts with a hyphen ('-')
and reject it early by throwing an AbortError. This prevents argument/option
injection attacks against git during initialization.
