feat(hyprland): add theme switching between dupre and hudson

Add two complete themes:
- dupre: warm earthy colors from Emacs dupre-theme.el
- hudson: Tomorrow Night + Goldenrod accent (original)

Theme files cover: foot, fuzzel, waybar, dunst, hyprland borders.

Add set-theme script with:
- set-theme <name>: apply a theme
- set-theme --toggle: switch between themes
- set-theme --pick: fuzzel picker

Keybindings:
- $mod Y: toggle theme
- $mod Shift Y: pick theme with fuzzel
