Add hermes-agent kit

[MonojitBanerjee]

Summary

• Adds a kind: agent kit for Hermes Agent by Nous Research — a self-improving AI agent that creates skills from experience, supports 200+ models, and includes a built-in
  cron scheduler and multi-platform gateway.
• Installs via the official install.sh in a detached background session; a polling entrypoint wrapper waits for the install flag before exec-ing hermes. Install logs land
  at ~/hermes-install.log.
• Supports three providers out of the box: Anthropic, OpenAI, and OpenRouter — each wired through the sandbox proxy.

Spec choices worth flagging

• Three credentials sources + proxyManaged — Hermes is multi-provider by design, so ANTHROPIC_API_KEY, OPENAI_API_KEY, and OPENROUTER_API_KEY are all declared. The user
  exports whichever key they have; sbx reads it via credentials.sources and the proxy injects it on outbound calls to the matching serviceDomain. Only the relevant key needs
  to be present.
• Background install with setsid — The official installer takes ~3–5 minutes (uv + Python 3.11 + pip install -e ".[all]"). Running it in a detached session keeps sandbox
  creation non-blocking, matching the pattern used by nanoclaw and openclaw.
• shell-docker base image — Hermes supports a Docker environment backend, so Docker-in-Docker availability in shell-docker is intentional.
• astral.sh in allowedDomains — needed for the uv installer; the binary itself is fetched from github.com/objects.githubusercontent.com which are also listed.

Test plan

• sbx kit validate ./hermes-agent/ — passes
• go test -v -count=1 -timeout 10m ./... — all 12 TCK subtests pass
• sbx run --kit ./hermes-agent/ hermes-agent — sandbox creates, installs, and launches hermes successfully
