"""
Cheshire Cat AI Adapter for Miku Discord Bot (Phase 3)

Routes messages through the Cheshire Cat pipeline for:
- Memory-augmented responses (episodic + declarative recall)
- Fact extraction and consolidation
- Per-user conversation isolation

Uses WebSocket for chat (per-user isolation via /ws/{user_id}).
Uses HTTP for memory management endpoints.
Falls back to query_llama() on failure for zero-downtime resilience.
