_fold_layouts folds siblings that share a structure into one row, and
_emit_group wrote its dir token from the first 40 members while
subtree_count and the folder count covered them all. Past forty, the
row claimed more than the link returned — the promise every other
count in this codebase keeps.
The group now stops at the cap, ranked, and the folders past it stay
their own rows. Measured on the gov.cy tree: seven layout groups, each
naming exactly what it counts.
endpoint_tree.py had no test. Its pure parts have one now: the fold,
the cap, the two refusals to group, the anomaly sentence and the
archive-only test.
