refactor(lint): fold the local collectionEntries copy into the #7186 helper

#7186 landed `packages/lint/src/collection-entries.ts` on main after this
branch was cut. The local 15-line duplicate documented as "folds into that
helper when it lands" now does — same semantics, same array/name-keyed-map
handling, same walk order, so no verdict or path changes.
