fix: update compose submodule for s6-overlay entrypoint crash fix

Updates the compose submodule to commit f4dd57f on branch
fix/hermes-s6-overlay-entrypoint-crash, which:

- Removes the broken entrypoint override (bash->tini->entrypoint.sh)
- Bakes start-hermes.sh into the image as the new CMD
- Uses the image default ENTRYPOINT (s6-overlay /init)

Fixes the SIGTERM restart loop on the Hermes container.

See compose PR #56 for details.

+# 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
+```
