## Summary

* **What is the goal of this PR?**
Add a debugging script to help developers monitor the ESP32 serial port
directly from a PC.

* **What changes are included?**
Added a new script: scripts/debugging_monitor.py

## Additional Context

While working on a new Crosspoint-Reader feature, it quickly became
clear that watching the ESP32 serial output without any visual cues was
inconvenient and easy to mess up.

This script improves the debugging experience by reading data from the
serial port and providing:

1. A timestamp prefix for every log line (instead of milliseconds since
power-up)
2. Color-coded output for different message types
3. A secondary window displaying a live graph of RAM usage, which is
especially useful for tracking the memory impact of new features

I wrote the initial version of the script. Gemini was used to help add
the Matplotlib-based graphing and threading logic.
