fix(CRITICAL): always deploy our qwen3_5.py — base image GDN also has NaN

Browse Source 
Base image qwen3_5.py (81706 bytes, 1777 lines) produces NaN frac=0.5000:
  CoreXGDN.__init__() got unexpected keyword argument 'num_v_heads'
  → all GDN layers fallback to base PyTorch GDN → NaN

Our qwen3_5.py has the xllm-aligned GDN fix (cumsum + difference form).
verify_single_card.py confirmed ZERO NaN on real BI-V100.

Remove conditional deploy — always overwrite base qwen3_5.py.
