Fix persistent OMP_NUM_THREADS override with unset + export

v1.4.5 - CRITICAL: OMP_NUM_THREADS still being overridden by HF
- HuggingFace keeps setting OMP_NUM_THREADS='3500m' despite Python override
- Added unset OMP_NUM_THREADS && export OMP_NUM_THREADS=1 in CMD
- Added debug echo to see actual value at startup
- This should prevent libgomp crash: 'Invalid value for environment variable'
