Compose the Sneak Attack arrival with the Bene Gesserit reactions

A positive Moritani Sneak Attack now resolves its committed Terror entry first —
placing the reserve forces and accruing the Heighliners token — and then offers
the Bene Gesserit reactions under the same adopted shipment classification used
for ordinary off-planet arrivals: an eligible Advanced Intrusion choice when
Bene Gesserit fighters stand in the destination, carrying the free
spiritual-advisor follow-up, and the advisor shipment itself when the intrusion
is declined, with its existing territory, storm and occupancy validation. A
zero-force resolution still opens none of them, and the last "Sneak Attack
combined with Bene Gesserit arrival reactions" guard is removed rather than left
as a duplicate check.

This selected order is an implementation interpretation, not a located ruling;
the source note, the pending-interpretation registry, the component inventory,
the player reference and the status log record it. Evidence:
tests/moritani-force-leader.test.ts asserts the post-entry Intrusion offer and
the full decline -> advisor decision -> placement chain with nothing left
pending; the former gated-interaction pin was replaced by the composed
behaviour. Offline suite 7,798/7,798 with typecheck and lint clean, plus the
reference guide tests 10/10. No game, seat, saved state or deployment changes.
