📚 Description

Nitro 3 no longer exposes the Nitro 2 and H3 entrypoints used by the server bundle. Route handlers now use nuxtseo-shared 5.3.8, with internal requests going through fetchWithEvent. The module aliases its own ofetch dependency for strict pnpm installs. A packed Nuxt 5 fixture covers route rules, robots.txt generation, and the debug route internal fetch.
