"""Run the Pashto resource update cycle in a repeatable way.

This script is a command wrapper around existing resource scripts so maintainers
do not need to remember the full sequence.

Usage:
    python scripts/run_resource_cycle.py
    python scripts/run_resource_cycle.py --limit 30
    python scripts/run_resource_cycle.py --skip-pytest
    python scripts/run_resource_cycle.py --discover-only
