feat: add Hyperspace Pods NixOS module and enable on lazyworkhorse

Hyperspace Pods let multiple machines pool their GPUs into one private P2P mesh AI cluster. Models are split across all connected GPUs — e.g. two machines with 16GB VRAM each can run Qwen 3.5 32B together. Changes: - Add modules/nixos/services/hyperspace.nix — NixOS module that: * Fetches the Hyperspace CLI binary (v5.45.30) via fetchurl * Sets up systemd service for the agent * Opens firewall ports (libp2p 4001, chain 30301, API 8080) * Configures GPU passthrough for AMD MI50 (ROCm) - Register module in flake.nix for lazyworkhorse - Enable hyperspace service on lazyworkhorse (ai-worker user, port 8080) Usage after deployment: hyperspace pod create "tdnde-lab" # create pod hyperspace pod invite # share invite with cyt-pi curl http://localhost:8080/v1/chat/completions # OpenAI API See skill: nixos-hyperspace-pods

+**Merge vs Phase Execution:**
+- PRs can merge independently (no strict phase ordering for merges)
+- **EXCEPTION:** Security hardening (#28) must merge before any new services are exposed
+- After security merge, deploy with: `nh os switch --flake .#lazyworkhorse`

 ## Build & Deployment

 - **Build/Deploy:** Use `nixos-rebuild switch --flake .#<hostname>` to build and deploy the configuration for a specific host.
- **CRITICAL — Validate before pushing:** Always `nix build --no-link '.#nixosConfigurations.<hostname>.config.system.build.toplevel'` (or `nh os build`) and confirm it succeeds before pushing any changes. Never push untested NixOS configs.
 - **Development Shell:** Activate the development environment with `nix develop`.

-# AI Worker Restricted Access
-
-This module provides SSH access for the AI worker (hermes-agent) to run ollama benchmarks on the host.
-
-## Security Model
-
-The `ai-worker` user has:
-
-### Filesystem Access
- **Home directory**: `/home/ai-worker` (standard user home)
- **No bind mounts**: Cannot access `/home/gortium/infra` or other host files
- **Cannot access**: Any files outside standard system paths
-
-### Sudo Access
- **NONE**: ai-worker has no sudo privileges
- Cannot run `nh`, `nixos-rebuild`, `nixpkgs-fmt`, or `nix` with elevated permissions
-
-### Docker Access
- Member of `docker` group - can run `docker` and `docker exec` commands
- Primary use: `docker exec ollama ollama ...` for benchmarking
- Can run `docker exec --privileged ollama rocm-smi ...` for VRAM monitoring
-
-## 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.
-
-### Example Workflow
-
-```bash
-# From Hermes container, SSH to host
-ssh -i /path/to/ssh/key ai-worker@host.docker.internal
-
-# On host, run ollama benchmarks via docker
-docker exec ollama ollama pull devstral-small-2:24b
-
-# Create test modelfile
-docker exec ollama bash -c 'cat <<EOF > /root/.ollama/test.modelfile
-FROM devstral-small-2:24b
-PARAMETER num_ctx 65536
-PARAMETER num_gpu 99
-PARAMETER flash_attn true
-EOF'
-
-# 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"
-
-# Check VRAM usage
-docker exec --privileged ollama rocm-smi --showmeminfo vram
-
-# Cleanup
-docker exec ollama ollama rm test-model
-
-# Exit SSH, return to Hermes container
-exit
-
-# Save results in Hermes container
-# /opt/data/ai-optimizer/state.json
-# /opt/data/ai-optimizer/results.csv
-```
-
-## SSH Access
-
-Connect as:
-```bash
-ssh ai-worker@lazyworkhorse
-```
-
-The working directory will be `/home/ai-worker`. No infra repo access.
-
-## Verification
-
-Check ai-worker permissions:
-```bash
-# On the host, as root or gortium:
-sudo -u ai-worker sudo -l
-# Should show: no sudo access
-
-# Check docker group membership
-groups ai-worker
-# Should show: ai-worker docker
-```
-
-## Troubleshooting
-
-If ai-worker cannot run docker commands:
-```bash
-# Check docker group membership
-groups ai-worker
-
-# Verify ollama container is running
-docker ps | grep ollama
-
-# Test docker access
-sudo -u ai-worker docker exec ollama ollama list
-```
-
-If SSH connection fails:
-```bash
-# Check SSH key is authorized
-cat /home/ai-worker/.ssh/authorized_keys
-
-# Check SSH service
-systemctl status sshd
-```
