Chat Tweaks - HeightFix

Feature: The position of the chat HUD has been adjusted slightly to prevent overlapping with the armor bar and other HUD elements. The chat is now placed 11px higher than in vanilla Minecraft, improving the visibility of both the chat and the lower UI components. This behavior is implemented using a @Redirect Mixin on ChatHud#render, modifying the return value of DrawContext#getScaledWindowHeight().
