Register connected altbots missing intents in the follow loop

Connected altbots whose AI was never attached by OnPlayerLogin (stale
core hook or is_bot false at login time) never got has_intents, so the
companion loop skipped them forever. Late-register them idempotently on
the next companion tick so they can follow without a relog.
