Connect Basic Tleilaxu to the full Leader Skills prototype

Admit genuine Basic Tleilaxu/base setup with the full fourteen-skill deck,
Ix card inventories and native three Face Dancers. Share public profile guards
across existing skill effects while retaining public-start and Advanced gates.

Record native own-leader skill offers at successful revival commitment so
automatic Tleilaxu response chains preserve the optional private draw. Connect
Rihani to unrevealed Face Dancer exchange with exact physical/status custody,
private controls and existing legal AI choices. Release completed Rihani's
live snapshot only after validated Face Dance admission; keep signed history
and current census checks. Zoal Smuggler uses opposing printed disc value at
reveal, excluding opposing skill bonuses and his separate revival value.

Add genuine setup, response/cancellation, private choice, custody, Face Dance
reset, Zoal, legal AI and authenticated concurrent recovery regressions. Add a
reproducible two-through-six-player sample profile and saved continuation.
Preserve unresolved skill effects, foreign-ghola boundaries and delayed AI tuning.

Validation: types, lint, 5,058 offline tests and production build passed.
Five full games completed with zero rejected actions and 74 JSON restores.
Browser QA CRY4DD4J used genuine setup and an explicitly conserved staged battle;
real Rihani draw/exchange and same-state refresh passed on mobile and desktop.
Screenshot capture timed out; full visual acceptance remains open. No HTTP
endpoint/auth/storage implementation changed; authenticated SQLite recovery was
verified. All 1,581 prior rooms, 3,349 seats and auxiliary records were preserved.
One new QA room/seat remains. No server restart, database reset or automation.

 alone. These boundaries are implementation limits, not prohibitions in the game.
