hermes config.yaml: add auxiliary LLM block pointing at mios-ai

Operator-flagged 2026-05-11 (inside the mios-hermes container shell
after running setup-hermes.sh): every agent invocation logs

    WARNING agent.auxiliary_client: Auxiliary auto-detect: no provider
        available (tried: openrouter, nous, local/custom, api-key)
    Compression, summarization, and memory flush will not work.
    Set OPENROUTER_API_KEY or configure a local model in config.yaml.

Hermes-Agent has two model slots:
  * `backend` -- the operator-facing chat model (already wired here
    to mios-ollama:11434 / qwen2.5-coder:7b)
  * `auxiliary` -- a separate model used for context compression,
    summarization, and memory flush. With no config block Hermes
    falls through openrouter/nous/local-custom/api-key and lands on
    nothing, so those features silently degrade.

Added an `auxiliary` block pointing at the same mios-ai (LocalAI
OpenAI-compatible /v1) surface every other MiOS AI client uses
(Architectural Law 5). Reuses the API_SERVER_KEY from
/etc/mios/hermes/api.env so we don't ship a second secret.
