3//! `localGit:pull(operationId, repoPath) -> bool`. Three-call
4//! sequence: read HEAD, `pull --ff-only`, read HEAD again.
5//! Returns `true` when the second HEAD differs from the first
6//! (i.e. the pull actually moved the branch). `--ff-only`
7//! avoids surprise merge commits - callers handle non-FF cases
8//! explicitly.
