Kitaru adapter builder

First select the smallest honest supported integration. Build an adapter inside the user's project only when no supported route meets the requested recording and replay boundary. Preserve the framework's public entrypoint and report exactly what the selected or custom adapter can observe, record, replay, and recover from.

Do not assume every framework can support the same fidelity. A useful result is either a locally tested adapter or a precise blocker tied to the installed versions and public hooks.
