Compose the deferred Terror arrival and green the mixed E3 programmes

Queue a committed Terror entry whose arrival also opened its own
interaction — Guild income, a Bene Gesserit fighter Intrusion or advisor
choice, or Fremen storm protection — in the additive
Game.pendingArrivalReaction list, and open the oldest queued entry from
settleAutomaticContinuations once nothing is pending. Payment, force
transfer and the original movement never replay; a Terror entry already in
flight and every Ambassador combination still reject.

Both withdrawn mixed E3 programme pairs are green: Moritani 9/9 and Ecaz
14/14, stable across 20 consecutive full-file runs. Their recorded resume
constraints became real fixture repairs, and the two restored consumer
omissions were corrected against the engine rather than re-pinned.

Repair pre-existing failures inherited at 45e6084 against current engine
behavior: stale Discovery and module gates in the native skills, Ix and
expansion-faction prototypes, the advanced Moritani skill boundary, the
Richese Nexus betrayal sale-credit expectation, one incidental gate
message and one flaky Collection-readiness assertion that reproduced at
HEAD.

Offline suite 7,793/7,793 with typecheck and lint clean. No game, seat,
saved-state, deployment, public-start or played-save conversion changes.
