push_grounding.py — Mac side. Sends grounding.md to Malin's 5090 grounding_receiver
so her long-term memory updates hands-free. Skips the push if nothing changed.

Usage:
  /usr/bin/python3 push_grounding.py            # push only if grounding.md changed
  /usr/bin/python3 push_grounding.py --force     # push regardless
