Style Optimization

Renamed Style Pack Optimization to Style Optimization while preserving the existing mod ID. Updated normal-player flight with smooth directional lean, sideways banking and look-following head stabilization. Fixed combined PAL/MPM item grip scaling for small players, matching the native classic/slim hand anchors. Added bounded weak box-shape reuse, large vanilla ingredient lookup and identifier hash caching with overlapping-mod guards. Improved NPC cache cleanup on entity/level exit. Added a one-time JVM-to-menu startup display, suppressed when Lightspeed provides it. Existing optimizations and compatibility fixes are retained. This release does not replace every external rendering, simulation or leak-fix mod.
