tooling(cutover): check:manifest-repository-directory names the ui/ manifests in its population declaration (objectstack#25803)

Bill item 21(b), measured: the self-test's DECLARATION ⊇ SCAN case printed only its first five
undeclared paths, which sort to ui/.objectstack-pin/*, so the run 8 reading looked like a pin
snapshot problem. Deleting the snapshot alone still leaves the 47 other ui/ manifests undeclared; the
declaration needs the ui/ root beside the other three. Spelled as check-workspace-manifest-cycles
spells the same population. With the self-test green the scan itself runs, and its findings are
the ui-side repository retarget patch.
