OptiFrames

Features

• Added config option to choose between OptiFrames optimized or vanilla item frame model rendering
• Added config option to render item frame back faces (optional, slight performance cost for improved vanilla parity)
• Removed item frame border rendering toggle (no performance impact, now always enabled)

Performance

• Combined border and back-face rendering into single render pass
• Frame model no longer rotates with map rotation (architectural fix)

Bug Fixes

• Fixed item frame borders rotating along with map rotation when using optimized model
• Fixed incorrect UV normals on frame border geometry causing visual artifacts
• Fixed glowing item frame borders rendering at full brightness instead of using proper light values
• Frame border textures now precisely match vanilla item frame model UVs
