## Summary
* Add a small loop in main to be able to receive external commands,
currently being sent via the debugging_monitor
* Implemented command: cmd:SCREENSHOT sends the currently displayed
screen to the monitor, which will then store it to screenshot.bmp
## Additional Context
I was getting annoyed with taking tilted/unsharp photos of the device
screen, so I added the ability to press Enter during the monitor
execution and type SCREENSHOT to send a command. Could be extended in
the future

## Summary
* I needed the ability to filter and or suppress debug messages
containig certain keywords (eg [GFX] for render related stuff)
* Update of debugging_monitor.py script for development work
## Additional Context
```
usage: debugging_monitor.py [-h] [--baud BAUD] [--filter FILTER] [--suppress SUPPRESS] [port]
ESP32 Monitor with Graph
positional arguments:
port Serial port
options:
-h, --help show this help message and exit
--baud BAUD Baud rate
--filter FILTER Only display lines containing this keyword (case-insensitive)
--suppress SUPPRESS Suppress lines containing this keyword (case-insensitive)
```
* plus a couple of platform specific defaults (port, pip style)

## 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

### AI Usage
Did you use AI tools to help write this code? _**< PARTIALLY >**_
I wrote the initial version of the script. Gemini was used to help add
the Matplotlib-based graphing and threading logic.
