Updates the @rocicorp/zero dev dependency (root and demos) to 1.12.0 and regenerates the lockfile. The peer range (^1.7.0) is unchanged.

This is part of the Zero 1.12 release smoke test. The pin was moved from the canary to the released 1.12.0 and the lockfile regenerated on 2026-11-12. It stays a draft until the checks have been rerun against 1.12.0; the results below are from the canary.

Checks run locally with pnpm 11.1.3: format --check, lint, check-types, test (11 files, 158 tests), build and the React demo's Playwright suite (48 tests, against a zero-cache started from this canary) pass.

The demos still pass userID: 'anon' for logged-out clients (demo/*/main.tsx), and this canary's client warns that this is deprecated and that the option should be omitted for logged-out clients. The demos keep working because their zero-cache doesn't verify JWTs, but dropping the fallback would silence the warning; that can go in this PR or a follow-up.

🔵 Needs a closer look

Approval is deferred because the documented checks used the canary rather than the released 1.12.0 lockfile, leaving the updated native/runtime dependency stack unverified.
