/**
 * evolution.js — Entry point for the OpenClaw Self-Evolution Daemon.
 * 
 * Usage:
 *   node evolution.js
 * 
 * Requires:
 *   - LLM configured (Ollama/OpenAI/Anthropic via .env)
 *   - GitHub token (GITHUB_TOKEN) for reading issues and creating PRs
 *   - GitHub repo (GITHUB_REPO) in 'owner/repo' format
 * 
 * The daemon will:
 *   1. Poll for proposals (GitHub Issues labeled 'evolution', local proposals.json)
 *   2. Evaluate each with an LLM judge
 *   3. Plan and implement approved changes
 *   4. Validate (syntax, imports)
 *   5. Create a PR or commit directly
