Adopt the Sneak Attack shipment classification for Heighliners

A positive Moritani Sneak Attack in Shipment and Movement now accrues the
Heighliners token once for its owner through the same techIncome helper as an
ordinary off-planet arrival. The token still enforces its working phase, its
printed Guild exception and one accrual per turn, and a zero-force resolution
accrues nothing; the previous phase-5 guard is removed rather than duplicated.

This is an explicitly adopted implementation interpretation, not a retrieved
publisher ruling: the printed verb is "Send", and classifying the expressly
off-planet reserve transfer as a shipment is the supported reading already
recorded in the source note. Bene Gesserit spiritual-advisor accompaniment and
Intrusion stay gated because their ordering inherits the unresolved
arrival-timing boundary; a Spice Blow worm-ride Sneak Attack stays outside the
token's working phase.

Evidence: tests/moritani-force-leader.test.ts asserts the accrual, the
once-per-turn guard, the unchanged zero-force resolution and the altered-sector
rejection; the former unsupported-classification pin was replaced by the
adopted behaviour rather than re-pinned. The component inventory, the source
note, the pending-interpretation registry, the player reference and the status
log record the reduced boundary. Offline suite 7,797/7,797 with typecheck and
lint clean. No game, seat, saved state or deployment changes.

 The common entry record binds the original entrant, territory, sector, cause, turn, phase and continuation. Current isolated paths cover ordinary movement, shipment, Guild cross-transport, accompanying advisors and worm rides; existing Moritani or allied entry does not offer Terror. When the same arrival would already need another response/decision, the engine rejects the complete attempted entry atomically instead of silently selecting a priority. No-Field placement/reveal distinctions remain source guidance until that separate subsystem exists. Worm continuation and temporary Truthtrance overlays have dedicated coverage in `tests/moritani-entry-overlays.test.ts`; they do not establish universal reaction ordering.

 ## Assassination pool: safe ordinary support
 
 Ordinary live native discs held by the entrant are the straightforward pool. Killing a disc already in the Tanks again, or awarding its strength again, is not supported. Do not award Moritani a player-chosen victim. Zoal's explicit payout must survive any generic strength calculation.
