Subject: [PATCH 1/2] fix: widen @json-render/react peer to React 18 and 19

The react peer range is now ^18.0.0 || ^19.0.0, and the lockfile
specifier matches it while the resolved version stays 19.2.4. The
installation page states that range alongside zod ^4.0.0, and the docs
baseline hashes for that page are updated to the new content. A vitest
reads the package manifest and expects peerDependencies.react to be
^18.0.0 || ^19.0.0, with react-dom left out of peerDependencies.

Fixes #329

Subject: [PATCH 2/2] fix: update pnpm lockfile for the widened react peer
 range

The previous commit set the react peer range in packages/react/package.json
to ^18.0.0 || ^19.0.0 but left the lockfile specifier at ^19.2.3, so
pnpm install --frozen-lockfile failed in CI. Regenerated with pnpm 11.1.3;
the resolved version stays 19.2.4.
