* fix(app-router): read indefinite app page cache entries App pages with revalidate=false currently normalize to Infinity, but the app-page cache read gate excludes Infinity. Pre-rendered static app pages can be seeded into the ISR cache and still miss that cache on every production request. The cache read policy now treats positive Infinity as read-eligible while preserving force-dynamic, production, RSC, and nonce guards. Cached indefinite responses are normalized to the same static one-year Cache-Control header used by fresh revalidate=false responses, so cache hits do not emit s-maxage=Infinity. Tests cover the dispatch cache hit path and the shared cached Cache-Control helper. * chore: rerun ci * chore: rerun ci
