This PR primarily fixes a resource leak created by using Files#walk outside of a try-with-resource statement. While I was here I also tried to clean up a few code smells, fixed the incorrect JAR manifest property names, and minorly optimized images. Tested the mod with these changes on Forge and Fabric using the potion brewing pack. I've left more details about each change in the commit message.
