MotoBot — the motos.cat assistant

The assistant that answers riders from any page of motos.cat. Each question goes through ordered layers: curated answers, semantic FAQ, retrieval on Qdrant (bge-m3 + reranker), generation with Gemini and GLM as fallback, and verification before serving. A 52-question reference set gates every release.
