Method fetch_submodule_changes

src/git.rs:944–972

Fetch submodule changes from the copied repository back to the original repository. This ensures that commits made by the agent in submodules are available in the original repo. The branch_name is used to create matching branch names in the submodule. Returns any non-fatal warnings encountered during the fetch.
