Subject: [PATCH] fix(fish): fit the fastfetch greeting to the terminal width

The greeting always drew the full NixOS logo beside the info block,
which overflows in a narrow terminal. Choose the logo by column count:
the full logo when it fits, the compact one when it does not, and none
below that.
