Kingdoms: Villager Retaliation!

Changed

• Made villager skill-trade registration idempotent so repeated registration passes no longer append duplicate offers to villager or wandering trader trade pools.
• Reworked interaction-screen layout math to be scale-aware across profile, skills, gift, navigation, option-list, and quest-journal UI surfaces.
• Tooltip rendering now uses bounded, scale-aware positioning so item and component tooltips stay readable and remain on-screen at larger UI scales.

Fixed

• Fixed UI scale rendering issues for gui scale 1, 2, 4, and auto.
• Fixed Mac user UI rendering (i think lol).
• Fixed duplicate villager and wandering-trader skill trades caused by repeated trade registration against mutable or previously registered trade collections.
• Fixed gift-page hit detection, hover states, and button placement drifting out of sync when UI scale or text scale changed.
• Fixed profile-page and option-list hover/click regions using unscaled screen coordinates, which could cause incorrect selection and tooltip behavior at non-default scales.
• Fixed interaction-screen tooltips rendering off-screen or at inconsistent positions when the UI was transformed or scaled.
