feat: remove unused voxtype dictation feature

Voxtype voice-typing was a full feature (5 scripts, a waybar widget, a
keybind, and a NixOS option) that this install does not use. The
nomarchy.system.voxtype option had no consumer — nothing read it — so the
widget and SUPER+CTRL+X bind were never actually gated by it.

Removes the scripts, default config, the SUPER+CTRL+X bind, the waybar
module (main + summer-night theme + css), the dead option, the installer
comment, and the docs. SCRIPTS.md/KEYBINDINGS.md regenerated; OPTIONS.md
and SKILL.md hand-updated.
