docs: remove aviso desnecessario sobre widget

fix: remove library_name: peft (Opcao B) + aviso no card sobre snippet incompleto do widget

fix: inference: false (HF widget nao suporta cross-encoder PEFT yes/no; snippet completo ja esta no card)

fix: limpa adapter_config fold_5 (remove campos PEFT 0.19+ que quebram widget HF)

fix: limpa adapter_config fold_4 (remove campos PEFT 0.19+ que quebram widget HF)

fix: limpa adapter_config fold_3 (remove campos PEFT 0.19+ que quebram widget HF)

fix: limpa adapter_config fold_2 (remove campos PEFT 0.19+ que quebram widget HF)

fix: limpa adapter_config fold_1 (remove campos PEFT 0.19+ que quebram widget HF)

feat: adiciona quickstart.ipynb (habilita badges Colab/Kaggle que estavam vazios)

fix: pipeline_tag text-generation (era text-classification, causando 'Task type is invalid' no widget PEFT)

docs: troca diagrama ASCII bi/cross por tabela comparativa (renderiza confiavel)

docs: card enxuto, tom confiante (remove secao de soup e limitacoes em lista)

docs: substitui adapter_souped experimental por resultado negativo honesto (soup-OOF degrada 21pp)

cleanup: remove examples/inference_souped.py (soup degradou 21pp macro-F1 sob soup-OOF)

cleanup: remove adapter_souped/adapter_model.safetensors (soup degradou 21pp macro-F1 sob soup-OOF)

cleanup: remove adapter_souped/adapter_config.json (soup degradou 21pp macro-F1 sob soup-OOF)

docs: card sobrio + justificativa tecnica do Qwen3-Reranker (cross-encoder vs bi-encoder)

docs: substitui placeholder GitHub por links HF reais na secao Reprodutibilidade

Initial release: 5 LoRA fold adapters + souped + model card
