Slay the Spire 2 nerfs card removal, buffs shivs, and adds a new reward system

Badges is a new in-run achievement system; badges mark unique run moments (e.g., beating bosses without losing health, finishing under a time, forgetting to spend gold, finding easter eggs) and appear at run end and in run history.

Inflation replaces the Gloom Ascension modifier at rest sites and raises the merchant card-removal price; it starts at 100 gold and increases by 50 gold each use.

Necrobinder's Borrowed Time was redesigned: it now grants four energy (six when upgraded) and raises all card costs by one for the turn to support high-cost cards like Reap and Bury.

History Course relic now uses current energy to determine its X value, while still playing its copy for free.

Blade of Ink now costs 1 and adds two Inky Shivs to hand (three when upgraded); Inky Shivs deal 6 damage and apply 1 Weak. Leading Strike now grants two Shivs instead of one.
