Removed .config/dot/.tmp from tracking: it was an empty 0-byte file
that had been committed by accident on another machine and was never
meant to be part of the repo.
Recorded fish_variables as it stands after first boot on this machine:
fish stamped __fish_initialized with its own version marker
(bootstrap bookkeeping, not user config) alongside the already-tracked
pure prompt theme, done plugin settings, and fisher plugin
registration.
