The limit() boundary used >=, so a subtree that fit the page exactly was
treated as overflow and dropped — under-filling the final page (e.g.
limit=5 over subtrees 3,2 returned only the first subtree, 3 comments,
instead of both). Change it to > so an exact-fit subtree is included;
the first node is still always returned in full and larger subtrees
still overflow to the next page.
Adds table tests for MakeTree's limit/offset pagination and countReplies,
and updates the /find consistent-count expectations for the corrected
boundary.
