Subject: [PATCH] test(cms): add regression test for site app detection on
 TanStack Start sites

TanStack Start's composeMeta does not register site/apps/site.ts in
manifest.blocks.apps, causing findSiteAppEntry to return null for
these sites. The canonical 'site' key is now trusted directly via
isSiteAppBlock. This test documents and guards that behavior.
