How RAG is loaded

1. These markdown files ship in the repo (and Docker image under knowledge/).
2. On app startup, knowledge_pack.py seeds every *.md (except README/SOURCES) into a shared Chroma session (__hea_knowledge_pack__) so advisors can retrieve Heidi's corpus without a manual upload.
3. Users can still upload extra .md / PDF files in chat; uploads stay session-scoped and are searched together with the bundled pack.
4. Persona system prompts (from Heidi's materials) also tell each advisor to treat reference materials as perspective-setting educational content, not medical authority.
5. Chroma collection + embedding model are configured in healthyeating_config.yaml → rag: (healthy_eating_documents, all-MiniLM-L6-v2).
6. When DATA_DIR is set (HF Spaces /data), Chroma persistence survives rebuilds.
