"""
CGAE Live Economy Server — ETH / 0G Chain

Runs the LiveSimulationRunner in a background thread and exposes
real-time state via REST endpoints for the dashboard.

Usage:
    python -m server.api                     # default 20 rounds
    python -m server.api --rounds 50
    python -m server.api --rounds -1         # infinite
