feat(training): LoRA sentiment + emotion pipelines complete
- Sentiment LoRA (FinBERT): 5 epochs, early stopping, 6.2MB adapter - Emotion LoRA (DistilRoBERTa): 5 epochs, weighted loss, 8.1MB adapter - Both with early stopping (patience=3, threshold=0.001) - Data augmentation: templates + crypto slang - Human-in-the-loop verification CLI - Disk-conscious: save_total_limit=1, ~6-8MB each

LoRA Fine-Tuning Pipeline for Crypto Emotion (Multi-Label)

- Base: j-hartmann/emotion-english-distilroberta-base (6 emotions)
|

- Multi-label classification (greed, fear, joy, anger, sadness, neutral)
|

- Crypto-specific emotion weighting (greed/fear emphasized)
|

- LoRA (r=8, alpha=16) on DistilRoBERTa
