20260907 BugFix

Fixed an issue where the placeholder text for Burn was not displaying correctly. Changed mechanics so that increasing Perception during a turn allows you to detect Mimic treasure chests. Optimized performance for displaying the play log. Adjusted and enhanced the "Call Bell" and "Savvy Shopper" skills. Added a display showing the coin count when selling items. Fixed an issue where achievements sometimes failed to register on Steam Deck. Added optimizations to prevent the game from slowing down as the number of items increases.
