feat: Treinamento Qwen3-0.6B Stage I com LoRA + Scripts de teste

## ✅ Treinamento Stage I Completo:
- **Duração**: 20 minutos
- **Loss**: 3.64 → 0.15 (95.9% redução)
- **Melhor checkpoint**: época 12 (loss 0.1476)
- **Dataset**: 500 samples (Common Voice PT)

## 📂 Estrutura Organizada:
- `scripts/`: Scripts de treinamento em background
- `tests/`: Todos os testes de validação
- `checkpoints/BEST_MODEL.md`: Referência ao melhor modelo
- `data/processed/`: Dataset preparado

## 🧪 Scripts de Teste:
- test_transcription.py: Transcrição básica
- test_audio_qa.py: Q&A com áudio
- test_simple_trained.py: Teste direto
- test_trained_with_embeddings.py: Com embeddings

## 📝 Nota:
Checkpoints não incluídos (>10MB). Use os scripts de treinamento para reproduzir.
