docs(spec): close stale $contains fold pointers for driver-memory (#7854) (#7890)

#7723 took the `i` flag off driver-memory's filterSubstringPattern,
closing #6682. Two packages/spec docblocks still pointed forward at
that landing as a future event:

- filter.zod.ts's per-backend history table (kept as history per
  #7625) had a driver-memory cell reading "the last one standing,
  until #6682" -- accurate as history, but the "until #6682" tail
  described a future that has since landed. Closed in past tense
  without flattening the historical framing; the table's other rows
  (including driver-mongodb's pre-#7625 mechanism) are untouched.
- filter-text-conformance.ts's @see #6682 line read "mongodb landed,
  memory open", contradicting the file's own header 37 lines earlier
  (already correct since #7723). Now reads "mongodb and memory both
  landed".

Fixes #7854

+docs(spec): close the stale `$contains` fold pointers in the `filter.zod.ts` per-backend history table and the `filter-text-conformance.ts` `@see` line
+
+#7723 took the `i` flag off `driver-memory`'s `filterSubstringPattern`, closing
+the #6682 tracking issue. Two docblock spots in `packages/spec` still pointed
+forward at that landing as if it hadn't happened yet:
+
+- `filter.zod.ts`'s per-backend history table (explicitly headed "measured …
+  BEFORE the ruling" — kept as history per #7625) had a `driver-memory` cell
+  reading "the last one standing, until #6682". The cell is historically
+  accurate (it WAS the last case-folding face when written) but the "until
+  #6682" tail described a future event that has since landed; it now reads
+  "the last one standing; #6682 closed it (see 'Implementation status'
+  below)". The table's other rows, including `driver-mongodb`'s, are left
+  untouched — they are correct as pre-ruling history and #7625 already judged
+  them that way.
+- `filter-text-conformance.ts`'s `@see #6682` line read "mongodb landed,
+  memory open", contradicting the same file's own header 37 lines earlier
+  (updated correctly by #7723), which already says the memory half landed
+  too. It now reads "mongodb and memory both landed".
+
+No behavior, schema, or generated baseline changes — these are TSDoc comments
+attached to exported schemas, which do reach `@objectstack/spec`'s published
+`dist/*.d.ts` (verified: `grep` on the rebuilt dist shows the edited sentence
+in `dist/filter.zod-*.d.ts`), so this ships as a patch changeset rather than
+`skip-changeset`.
