A point in history (tag name) where I'm happy

This is mostly a fine config. There is a little bit of a rough patch
regarding the return key and nvim-cmp, where it can be a little invasive
and insert unwanted text. It mostly stays out of the way though.

From this point on I'll be very aggressive on reducing plugin quantity,
reducing vimscript-based plugins and trying out good old plugins like
telescope. I'm making this tag so that I have a safe place to go back in
case I screw something up during work hours
