v2.5.23: Merge pull request #438 from AInVFX/main

• 🔒 Security: Prevent code execution in model loading - Added protection against malicious .pth files by restricting deserialization to tensors only
• 🎥 Fix: FFmpeg video writer reliability - Resolved ffmpeg process hanging issues by redirecting stderr and adding buffer flush, with improved error messages for debugging (thanks @thehhmdb)
• ⚡ Fix: GGUF VAE model support - Enabled automatic weight dequantization for convolution operations, making GGUF-quantized VAE models fully functional (thanks @naxci1)
• 🛡️ Fix: VAE slicing edge cases - Protected against division by zero crashes when using small split sizes with high temporal downsampling (thanks @naxci1)
• 🎨 Fix: LAB color transfer precision - Resolved dtype mismatch errors during video upscaling by ensuring consistent float types before matrix operations
• 🔧 Fix: PyTorch 2.9+ compatibility - Extended Conv3d memory workaround to all PyTorch 2.9+ versions, fixing 3x VRAM usage on newer PyTorch releases
• 📦 Fix: Bitsandbytes compatibility - Added ValueError exception handling for Intel Gaudi version detection failures on non-Gaudi systems
• 🍎 MPS: Memory optimization - Reduced memory usage during encode/decode operations on Apple Silicon (thanks @s-cerevisiae)
