Owner

Implement the backend server and Pi Agent integration.

Acceptance Criteria

backend/src/config.ts — loads config.yaml with env var interpolation
backend/src/vectordb.ts — LanceDB Node.js client for hybrid search
backend/src/tools.ts — dnd_rules_search tool, roll_dice tool
backend/src/prompts.ts — Reference mode, DM mode, and OOC handler prompts
backend/src/agent.ts — Agent factory with transformContext RAG injection
backend/src/ws.ts — WebSocket handler streaming agent events
backend/src/index.ts — Hono server with REST + WS endpoints
backend/src/routes/api.ts — REST endpoints for search, dice, config
shared/src/types.ts — shared types (messages, config schema)
shared/src/dice.ts — dice notation parser (XdY+Z, kh/kl, etc.)
TypeScript compiles without errors

Files to Create/Modify

backend/src/*.ts
shared/src/*.ts
backend/package.json (update deps as needed)

See project.md sections 3, 5, 6, 7, 12 for full spec.
