docs: Complete local AI stack documentation

- Deployed Ollama + Open WebUI on Unraid
- Created custom unraid-assistant model with full infrastructure knowledge:
  - Network topology (8 VLANs, all IPs/gateways)
  - 45+ Docker containers with ports and purposes
  - RouterOS 7 commands and VLAN patterns
  - Traefik labels and Authentik SSO middleware
  - All xtrm-lab.org external URLs
- Added /usr/local/bin/ai terminal helper command
- Documented RAM optimization (stopped 5 containers)
- Added future upgrade notes for Mac Mini M4

+## Custom Model: unraid-assistant
+
+A fine-tuned system prompt model that knows the xtrm-lab.org infrastructure:
+
+### Knowledge Included
+- **Network topology**: All VLANs (10,20,25,30,31,35,40,50), IPs, gateways
+- **45+ Docker containers**: Names, images, ports, purposes
+- **RouterOS 7**: Commands, VLAN patterns, firewall rules
+- **Traefik**: Labels, routing, SSL configuration
+- **Authentik**: SSO middleware, provider setup
+- **External URLs**: All xtrm-lab.org services
+
+### Usage
+
+```bash
+# Terminal (SSH to Unraid)
+ai "How do I add a device to the IoT VLAN?"
+ai "What port is gitea running on?"
+ai "Show me Traefik labels for a new app with Authentik"
+
+# Interactive mode
+ai
+```
+
+### Rebuild Model
+
+If infrastructure changes, update and rebuild:
+
+```bash
+# Edit the Modelfile
+nano /mnt/user/appdata/ollama/Modelfile-unraid
+
+# Rebuild
+docker exec ollama ollama create unraid-assistant -f /root/.ollama/Modelfile-unraid

-## Future Considerations
+## Open WebUI RAG Setup
 
-- **More RAM:** With 32GB+ RAM, could run larger models (14b, 32b)
-- **Dedicated GPU:** Would significantly improve inference speed
-- **Additional models:** Can pull more models as needed with `docker exec ollama ollama pull <model>`

+2. **Workspace** → **Knowledge** → **+ Create**
+3. Name: `Infrastructure`
+4. Upload docs from `/mnt/user/appdata/open-webui/docs/`

+## Future: Mac Mini M4 Upgrade
+
+Planning to migrate AI stack to Mac Mini M4 (32GB):
+
+| Metric | N100 (current) | M4 (planned) |
+|--------|----------------|--------------|
+| Speed | ~1 tok/s | ~15-20 tok/s |
+| Max model | 7B | 70B+ |
+| Response time | 30-90s | 3-5s |
+
+The M4 unified memory architecture is ideal for LLM inference.
