Theme-linked glow and terminal, tabs, fonts and layout tweaks

- Real window glow (decoration.glow) plus borders and tab bar take their
  colours from DMS (hypr/dms/colors.lua); Hyprland reloads when DMS changes
  the theme.
- kitty: colours and tab colours come from DMS (dank-theme/dank-tabs),
  no more hard-coded palette.
- Group (tab) mode: Mod+W tabs the whole workspace, thinner tab bar.
- Fullscreen programs keep the DMS bar (Mod+F maximizes, Mod+Shift+F is real
  fullscreen); per-monitor workspace switching on Mod+Tab.
- Less jelly animations, smaller gaps, weaker glow.
- JetBrains Mono is the default monospace font (fontconfig + install.sh).
- DMS settings: purple theme, popup transparency 0.98.
