Problem

PR #7950 added Docker/Podman/Lima DNS name detection to is_local_endpoint() — these hostnames now auto-trigger relaxed streaming timeouts. But the docs don't mention this anywhere:

• docker.md has no section about connecting to a host-side LLM (Ollama, llama.cpp, etc.) from inside a Hermes container
• local-llm-on-mac.md Timeouts section says "localhost, LAN IPs" but doesn't mention host.docker.internal and friends

User impact

A user running Hermes in Docker + Ollama on the host has no docs guidance on:

1. Which hostname to use (host.docker.internal vs localhost — the latter won't work from inside Docker)
2. That Hermes auto-detects these hostnames as local (no manual timeout config needed)

Proposed fix

1. Add a "Connecting to local LLMs on the host" section to docker.md with a hostname table (Docker/Podman/Lima) and a config example
2. Update the auto-detection description in local-llm-on-mac.md Timeouts section to mention container DNS names
