Add Atomic Chat Integration

This skill adds a stdio-based MCP server that exposes models running in the local Atomic Chat desktop app as tools for the container agent. Claude remains the orchestrator but can offload work to local models served by Atomic Chat on http://127.0.0.1:1337/v1 (OpenAI-compatible).

Tools exposed:

• atomic_chat_list_models — list models currently available in Atomic Chat (GET /v1/models)
• atomic_chat_generate — send a prompt to a specified model and return the response (POST /v1/chat/completions)

Model management (download, delete) is done through the Atomic Chat desktop UI — the app is a fork of Jan and manages its own model library.

The skill ships the MCP server source (and its test) in this folder and copies them into the agent-runner tree at install time, then registers the server in index.ts and forwards host env vars in container-runner.ts. Registering the server is enough to expose its tools — the agent's allow-pattern (mcp__atomic_chat__*) is derived from the registered server name.

Phase 1: Pre-flight

Check if already applied

Check if container/agent-runner/src/atomic-chat-mcp-stdio.ts exists. If it does, skip to Phase 3 (Configure).
