project: don't rerun git status after a failed snapshot

When a status snapshot fails, fall back directly to _IsDirtyLegacy()
instead of IsDirty() to avoid running git status twice.

Expose Project.GetDirtyAndHead() so sync bloat checks can inspect
worktree state without invoking private Project methods.
