The new subdomain pages 404ed in production: the vercel.json host
rewrites do not fire — SSR sees /agents, never /nook/agents — so pages
that only exist under src/routes/nook/* are unreachable from the
subdomain. Every pre-existing subdomain surface survives on top-level
host-dispatch routes (index, privacy, checkout, deletion), which is why
only the new pages broke. Give the three pages the same dispatch,
falling back to 404 on other sites.
Tests: full bun test run unchanged (539 pass); vinxi build clean.
Issue: FRE-12
