Method set_git_town_parent

src/git.rs:547–575

Set git-town parent branch configuration This writes to git config without triggering any git operations. Should be called within a repo lock to prevent concurrent config writes. # Arguments `repo_path` - Path to the repository where the config should be set `branch_name` - Name of the branch to set the parent for `parent_branch` - Name of the parent branch
