AI Integration

• Multi-Provider Fallback Chain: AIClient tries LocalAI first, then falls back through OpenCode → MiniMax → Kimi automatically on failure or misconfiguration.
• Page Generation Pipeline: Discord messages are grouped by semantic similarity, analyzed by AI, and written as structured wiki pages complete with tags, metadata, and cross-links to related pages.
• Vector Embeddings: 1024-dimensional embeddings generated for every page and stored via pgvector. Cosine similarity search now works end-to-end.
• Relationship Discovery: AI analyzes page pairs to discover semantic, hierarchical, and reference relationships — building the knowledge graph automatically.
• Daily Cron Job: Automated knowledge extraction runs at 1 AM CET via tokio-cron-scheduler. No manual triggers needed.
