feat: Add Oghma RAG Proxy for SkyrimNet lore injection

RAG proxy that intercepts SkyrimNet LLM requests and enriches them
with relevant Tamrielic lore from CHIM's Oghma Infinium database.

Features:
- FastAPI proxy compatible with OpenAI API
- ChromaDB semantic search for lore retrieval
- NPC profile extraction from SkyrimNet prompts
- Google Sheets ingestion for CHIM's Oghma data
- Kubernetes deployment manifests
- Debug endpoint for RAG operation monitoring

Collections ingested to iris-dev ChromaDB:
- oghma_lore: 1951 entries (scholar knowledge)
- oghma_basic: 1949 entries (commoner knowledge)
- oghma_visual: 1151 entries (Omnisight perception)
