Prototype Sapho first after completed movement turns

Allow a physical Sapho holder to go first among remaining unstarted combined
shipment/movement turns after earlier players have fully finished. Preserve
completed resources, cards, counters and physical order. Keep Advanced Guild
priority guarded until Guild leaves the remaining queue. Reuse private controls,
all four AI profiles and the existing action/CAS continuation.

Add four engine regressions and one independently authored SQLite recovery race;
upgrade the existing Sapho Advanced engine fixture to genuine Advanced setup.
Update player guidance and the rules decision register. Record the fourteen
Leader Skill cards and lifecycle as sourced future work, with unresolved edges.
No mode or publication gates are opened.

Validation: check (types, lint, 4,369 offline tests) and build passed. All 35 focused
Sapho tests passed; independent engine/persistence review found no blocker.
One initial focused Advanced test omitted the existing Guild shipment approval;
it was corrected to resolve that real decision before ending the turn.
No HTTP/auth/schema change; the HTTP suite was not repeated for this checkpoint.

Following the reported power outage, the existing localhost server was healthy,
SQLite integrity/foreign-key checks passed, and the saved QA seat restored the
same private hand, forces, resources and pending Storm decision after refresh.
All 291 opening room versions/state hashes and all application seat/recovery/
entry/handover records match the fresh backup. Cloudflare internal metadata
changed; application data did not. No restart or database reset was needed.
