Add a SessionsSnapshot view over the new C ABI entry point and serve it from the admin server as GET /rc-sessions. The admin server gains a WithAdminRoute option so an embedding binary can register extra admin routes that run with the same signature verification and admin checks as the built-in endpoints; vgwrdma registers the snapshot there when the RC feature is enabled. The route replies with the usual XML error surface so unsigned or non-admin requests get a 403 rather than a generic 500. Stub builds return a not supported error, keeping the build matrix unchanged.
