cluster-only warns when --backend/--model/--batch-size are ignored on the
label-reuse path; the community-label prompt key no longer collides with
the discard sentinel (an echoed key was silently dropped); tree --root
exits non-zero when it matches no source file instead of flattening the
tree; and cluster-only stamps built_at_commit from the analysed graph, not
the shell cwd. Also folds in the cluster-only refused-write guard from
PR #2522 (thanks @aniJani).
Thanks @elecnix for the report.
