// Generate Hermes config.yaml and .env from NemoClaw build-arg env vars.
//
// Called at Docker image build time. Reads NEMOCLAW_* env vars and writes:
//   ~/.hermes/config.yaml  — Hermes configuration (immutable at runtime)
//   ~/.hermes/.env         — Messaging token placeholders (immutable at runtime)
//
// Sets what's required for Hermes to run inside OpenShell:
//   - Model and inference endpoint (custom provider pointing at inference.local)
//   - API server on internal port (socat forwards to public port)
//   - Messaging platform tokens (if configured during onboard)
//   - Agent defaults (terminal, memory, skills, display)
