project: use one status snapshot for dirty checks

On Git 2.11 and newer, replace update-index, diff-index, diff-files, and
ls-files fan-out with one porcelain-v2 snapshot for IsDirty,
UncommittedFiles, and HasChanges. Preserve category ordering and
duplicate staged-plus-unstaged paths, and keep the exact legacy path for
older Git or a failed snapshot.
