* optimise zplug, completions and ohmyzsh plugin loading resulting in
faster load time
* introduce shell caching (surely another speed-up)
* clean-up zshrc and move stuff (wayland exports, sway call) to profile
* set cleaner git status indicators via SPACESHIP vars
* delete stuff (yeah, I know...)
as per #2
* add gradle completion plugin
* fix asdf completions
* add dotnet completions
* set autosuggest strategy to both history and completion (again)
* add ix() function
* fix upload function
* rm yarn from ohmyzsh plugins
