Subject: [PATCH] Add HALO Debug Pack - AMD ROCm bf16 diagnostic tools

Adds diagnostic nodes for debugging black image issues caused by
numpy's lack of bfloat16 support on AMD ROCm, older NVIDIA cards,
Apple Silicon, and unified memory systems.

Nodes included:
- HALO VAE Decode/Encode (FP32) - forces fp32 to fix bf16 conversion
- HALO Latent Debug - check sampler output for NaN
- HALO Conditioning Debug - check text encoder for NaN
- HALO Model Debug - inspect model dtype
