Disable tracker3

This service is responsible to collect file information in your home directory to allow for better search results. It may be very inconvinient if you're working with huge or many changing files in that directory, e.g. when cosing or working with AIs.

sudo systemctl --global mask tracker-miner-fs-3.service
sudo systemctl --global mask tracker-xdg-portal-3.service

Then for all users:

tracker3 reset -s -r
rm -rf ~/.cache/tracker
