feat(theme): finish neon-glass polish (#88)

Rewrite whole-swap rofi.rasi to rofi-native @colors (was invalid CSS
var()); cyan glass panel matching Boreal's hex-alpha pattern. btop
titles/selection in accent cyan; ui rounding/opacity tuned; preview.png
from theme-shot. Bar stays generated from JSON (no waybar.css).

Verified: V2 — contrast 24×7; theme-wholeswap; theme-shot neon-glass
desktop+menu viewed; boreal theme-shot regression green.
