[RFC] Make it work on RaspberryPi OS Trixie

[ozbenh]

Hi ! Not an expert at python packaging but here we go ... A few things in there, small .gitattributes fix, turning regexp strings into r"" strings so newer python (3.14 here) doesn't barf, and finally always use a venv to install the pip dependencies, because otherwise hell breaks lose on any modern system.

This is rough. Will probably break older systems, I don't really know what I'm doing here :-) Happy to adapt based on feedback.

For make install I chose for now to copy the whole source over to /home/twcmanager to be able to properly pip install into the venv from there. There might be a better way... this works :-) I've added a modified systemd service file to run it that way (seems to work on dummy for now, I'll try on the real charger when I get back near it).

We should update docs/Software_Manual.md with explicit instructions for Trixie

Right but I'm thinking maybe I should default to USE_VENV?=0 and make the instructions explicit about using make USE_VENV=1 for Trixie ? I worry I can't test this isn't breaking existing workloads otherwise

Thanks for the PR. No need to default back to VENV=0 I would say, it's essentially a core requirement for the apt ecosystem now, unless there were any objections I'd suggest we just do it by default.

I finally got a chance to try it on the real charger today rather than in "fake" mode and it didn't actually work. I have to stick to 'b' not 'r' for the regexps as the msg is binary. I will look into this more later to figure why I had to change it in the first place, for now don't merge this.

Converted to draft. I will polish this once I've actually moved into the new place where the charger is and can test more fully
