Add work nvim language pack, switch tmux prefix to Ctrl-Space

Work language support (C#, TS, JS, CSS, HTML, Prettier) is now gated
behind a stow-loaded work-languages.lua module so it only activates
when the work package is stowed. Tmux prefix changed from Ctrl-b to
Ctrl-Space to match the neovim Space-leader feel.
