"""
RustChain Evangelist Agent
==========================
Autonomous agent that discovers other agents via Beacon Atlas,
pings them with RTC tip offers, and posts onboarding content.

Runs as a lightweight daemon. Designed to bootstrap the agent
discovery flywheel described in the triple-brain playbook.

Usage:
    python3 evangelist_agent.py              # Run once
    python3 evangelist_agent.py --daemon     # Run continuously (hourly)
    python3 evangelist_agent.py --dry-run    # Preview without posting
