# Safe to run every time. It will:
#   1. install the Koretex node (engine + agent + auto-start service) if it isn't already,
#   2. enroll a self-custody wallet (mints a node token to EARN + a customer key to SPEND),
#   3. pick & serve the highest-demand model this machine can host,
#   4. make sure the node is running,
#   5. print a JSON summary (between ===KORETEX-JSON=== markers) for the caller to configure
#      this machine's own inference against Koretex.
#
# It NEVER prints the customer API key — only the path to the file that holds it (0600).
# Override the network with KORETEX_DISPATCHER (defaults to production).
