chore(layering): declare the deferred-warning latch owner and ratchet baseline

The R7 session-state gate requires every SessionState field to have a
declared writer owner: recoveredSnapshotWarningLatch is owned solely by
snapshot-quality-latch.ts (matching the field's 'managed only through'
contract), and the R10 pressure baseline grows deliberately to
23 writer-owned fields / 29 owner claims. Also oxfmt-formats the new
latch test.
