Adds an influence currency that scales with follower count and a new
"exert influence" action to trade it for secrecy, uncaps recruiting
with scaling cost, adds a late-game Andakt sink, and makes hemlighet
drain scale with dread/ritual progress so the endgame carries real
risk. Includes a Vitest suite that simulates play to check balance,
which caught the influence-accrual rate being too slow to be useful
early game.
