fix(mothership): terminal predicate import must not pull the session barrel into the client

The #9 dedup pointed use-chat (a 'use client' graph) at the session
BARREL, which reaches ioredis via the buffer — Next resolved 'dns' in a
client bundle and the whole dev server 500ed. Client consumers deep-import
the client-safe contract module; the barrel export stays for the server.
Caught by an end-to-end smoke, not by tsc/vitest/boundary-check — none of
them walk the client bundle graph.
