v16.0.8

• Pages Router: self-diagnosing serverSideTranslations error — the "Initial locale argument was not passed into serverSideTranslations" error now names its two common causes (missing i18n section in next.config.js; pages rendered outside Next.js locale routing such as custom 404/500 or output: 'export') and shows the explicit-locale fix inline.
• CI: weekly Next.js compatibility workflow — builds and e2e-tests all example apps against next@latest and next@canary on a weekly schedule (plus manual dispatch), so upstream Next.js regressions like the 13.5.4 bundling breakage (#2214) surface within days instead of via user reports.
