Docker production build runs without DATABASE_URL, so any page Next
tries to prerender at build (force-static / revalidate without a
dynamic segment) fails on the Prisma call. Homepage, genre page, and
sitemap previously had page-level revalidate, forcing prerender. Add
force-dynamic to each and move the revalidation inside an
unstable_cache wrapper around the Prisma query — result still cached
5m / 1h at runtime, but build no longer touches the DB.
Detail page (/manga/[slug]) keeps page-level revalidate since its
dynamic segment without generateStaticParams was never prerendered at
build anyway.
Update CLAUDE.md caching section to reflect the new strategy.

Stable image URLs (post-signing removal) make page-level caching
safe again. Homepage, genre page, sitemap, and detail page now
revalidate on an interval instead of running Prisma on every hit.
Reader and search keep dynamic rendering (searchParams) but wrap
their Prisma queries in unstable_cache.
TTLs: home/genre/detail 5m, reader manga 5m, reader page meta 1h
(immutable), search 1m, sitemap 1h.
