Connect Leader Skill battle effects and private Rihani exchanges

Prototype Mentat/Bureaucrat score effects, automatic Sandmaster board spice, and Rihani inspection plus committed exchange. Preserve private views, physical custody, saved winner cleanup and captive/Suk sequencing. Remaining normal bands, missing skill families and combined modules remain gated.

Validation: 45 focused tests; typecheck, lint, 4465 offline tests, production build and 43 HTTP tests passed. Independent rules/privacy/persistence review completed. New isolated browser setup exercised inspection, draw, pending refresh, exchange and completed refresh. Two genuine four-profile Basic/Advanced samples completed without rejected candidates but did not trigger Rihani.

Preserved all 393 opening rooms and original seat/recovery rows (427 rooms after QA/HTTP). SQLite integrity and foreign keys passed. Server remained healthy after the reported outage; no restart or reset.
