Stamina For Tweakers

Changed

• Refactored (and drastically simplified) the code for stamina display update smoothing.
• Now the Tirelessness effect changes the color of the stamina bar rather than the bar outline. This works better on 1.21.1 until I can do a complete refactor to account for differences in the HUD render layering.

Fixed

• Fixed an issue where the player could sometimes recover stamina while walking even when that option was disabled due to a janky numeric comparison.
• Now accounts for the offhand item slot in the hotbar if using Centered icon alignment and the icon would overlap.
• Fixed logic error that prevented recoverWhileSneaking from working.
