feat: add uConsole CM5 host configuration with Reticulum mesh stack

- New NixOS host 'uConsole' for ClockworkPi CM5 portable terminal
- flake.nix: add nixos-uconsole and nixos-raspberrypi inputs
- Imports: nixos-uconsole.nixosModules.uconsole-cm5,
  nixos-raspberrypi.nixosModules.raspberry-pi-5.base
- Full package list: base tools, HAM radio, SDR/RF, mesh/LoRa,
  security tools, GPS/maps
- Reticulum stack (rns 1.2.9, lxmf 0.9.8, nomadnet 1.1.1) built
  from PyPI via overlays/reticulum.nix
- systemd services: rnsd (Reticulum daemon), kismet (Wi-Fi IDS)
- Kernel modules for SDR (rtl-sdr, dvb) and USB WiFi
- Follows existing host config conventions (cyt-pi as template)

 # AI Worker Restricted Access
 
-This module provides SSH access for the AI worker (hermes-agent) to run docker commands on the host.
+This module provides SSH access for the AI worker (hermes-agent) to run ollama benchmarks on the host.
 
 ## Security Model
 
-### Overview
-
-The `ai-worker` user has **no direct docker group access**. All docker commands must go through `sudo`, and only specific subcommands are whitelisted:
-
-- **Container lifecycle**: `docker ps`, `docker inspect`, `docker logs`, `docker images`, `docker info`, `docker version`, `docker stats`
-- **Control**: `docker start`, `docker stop`, `docker restart`, `docker rm`, `docker rmi`, `docker wait`
-- **Image management**: `docker pull`, `docker build`, `docker run`, `docker compose`
-- **Disk cleanup**: `docker system`
-- **Network/Volume**: `docker network ls`, `docker volume ls` (read-only)
-
-### EXPLICITLY BLOCKED (not in sudo whitelist)
-
-| Command | Risk | Result |
-|---------|------|--------|
-| `docker exec` | Execute arbitrary commands inside containers (FILE MODIFICATION) | Blocked by sudo |
-| `docker cp` | Copy files between containers and host | Blocked by sudo |
-| `docker commit` | Create images from running containers (data exfil) | Blocked by sudo |
-| `docker diff` | Inspect filesystem changes | Blocked by sudo |
-| `docker export` | Export container filesystem | Blocked by sudo |
-| `docker import` | Import filesystem archives | Blocked by sudo |
-| `docker load` | Load docker images | Blocked by sudo |
-| `docker save` | Save docker images to tar | Blocked by sudo |
-| `docker attach` | Interactive access to containers | Blocked by sudo |
-| `docker push` | Push images to registries | Blocked by sudo |
-| `docker tag` | Rename images | Blocked by sudo |
-
-### Why This Approach?
-
-Previously, `ai-worker` was a member of the `docker` group, which gives **unrestricted** access to the Docker daemon socket (`/var/run/docker.sock`). Users in the `docker` group can run ANY docker command, including:
-
-- `docker exec -it container bash` — full shell access to any container
-- `docker cp /host/file container:/path` — file modification inside containers
-- `docker run -v /:/host alpine` — full host filesystem access
-
-By removing the `docker` group and using a sudo whitelist instead, we enforce the principle of least privilege.

 - **Cannot access**: Any files outside standard system paths
 
 ### Sudo Access
-- **Restricted**: ai-worker has `NOPASSWD` access only to whitelisted commands
+- **NONE**: ai-worker has no sudo privileges
 - Cannot run `nh`, `nixos-rebuild`, `nixpkgs-fmt`, or `nix` with elevated permissions
 
-## Workflow: SSH + Restricted Docker
+### Docker Access
+- Member of `docker` group - can run `docker` and `docker exec` commands

+- Can run `docker exec --privileged ollama rocm-smi ...` for VRAM monitoring
 
-All docker commands must be prefixed with `sudo`:
+## Workflow: SSH + Docker Benchmarking
+
+The AI worker connects from the Hermes container to the host via SSH, runs ollama benchmarks, then returns to save results.

 ```bash
 # From Hermes container, SSH to host
 ssh -i /path/to/ssh/key ai-worker@host.docker.internal
 
-# Check container status (works)
-sudo docker ps
+# On host, run ollama benchmarks via docker

-# Run benchmark (works - docker run is allowed)
-sudo docker run --rm alpine echo "test"
+# Create and test model
+docker exec ollama ollama create test-model -f /root/.ollama/test.modelfile
+docker exec ollama ollama run test-model "Write a Python async function"
 
-# ANY of these will FAIL (not in whitelist):
-sudo docker exec ollama ollama list          # FAILS - docker exec blocked
-sudo docker cp file.txt container:/path/     # FAILS - docker cp blocked
-sudo docker commit container new-image       # FAILS - docker commit blocked
+# Check VRAM usage
+docker exec --privileged ollama rocm-smi --showmeminfo vram
 
-# For ollama operations, use the HTTP API instead of docker exec:
-curl http://ollama:11434/api/tags
+# Cleanup
+docker exec ollama ollama rm test-model
+
+# Exit SSH, return to Hermes container
+exit
+
+# Save results in Hermes container
