Split laptop/work into independent stow packages with shared/ base

- Remove work/laptop detection logic from nvim and emacs configs; each
  package now has a self-contained init that requires no runtime checks
- Create shared/ stow package containing nvim/init.lua, emacs/init.el,
  common-dev-settings.el, org-bindings.el, tmux, ghostty, and ranger
- Rename laptop-languages.lua / work-languages.lua → languages.lua in
  each package; shared/init.lua uses require('languages') generically
- Rename work-dev-settings.el → dev-settings.el to match laptop naming
- Expand work/ to include the full set of dev tools (tmux, ghostty,
  ranger, emacs, neovim) without email/calendar tooling
- Add Makefile with `make laptop` and `make work` targets (each runs
  a single `stow shared <profile>` invocation)
