Function current_branch

src/branch.rs:12–25

Resolves the current branch name using `gix`. Falls back to `git symbolic-ref HEAD` for worktrees when gix cannot resolve HEAD (e.g. with minimal feature flags that exclude worktree support). Returns `None` for detached HEAD or if the repository cannot be opened.
