move_simple.py

# examples/basic/move_simple.py
#
# Demonstrates: a simple move using move() — no hardware needed
# API style: call move() on every loop iteration
# Async equivalent: examples/async/move_simple.py

#
# move() returns (position, running, changed). Call it in a while loop
# until running is False — each call advances the move by one step.
