- Move global-display-line-numbers-mode from early-init.el to init.el
- Slim down init-kbd.el: remove hydra-multiple-cursors, migrate defs
- Reorganize dirvish config
- Remove scattered global-set-key bindings from init-org, init-ui, etc.
- Guard server-start with server-running-p check
- Set ibuffer-default-sorting-mode to filename
- Tweak gptel config
