chore(cutover): the happy-dom floor's comment names the objectui lines it moves (objectstack#25803)

scripts/ui-import/README.md step 6: after the splice, every objectui row still moved must be an
override pnpm-workspace.yaml keeps on purpose, named in its comment block. Measured with
`splice-lockfile.mjs --measure` against objectui main 3b7b040 (subtree-pulled onto
9e37acd): 48 rows moved; 46 are the `pnpm dedupe` moves the cutover recipe accepts (item 16),
and the other two are happy-dom 20.11.2 -> 21.0.4 in ui/ and ui/apps/console, which this floor
(GHSA-834v-8h66-3h79, no 20.x fix) makes. The react-router floor was already scoped to 8.x
(objectui's 7.x line moves 0 rows) and better-auth no longer moves, since objectui declares
1.7.12 itself.

The happy-dom comment still said no manifest declares it and the lockfile carries none, which is
true of objectstack alone and false of the merged tree. Comment only: the override and the lock
are unchanged (`pnpm install --lockfile-only` leaves pnpm-lock.yaml byte-identical), and
check:override-consistency, check-osv-exemptions and check-watch-hint-literal exit 0.
