Cadence 3.4.4

• Fix: since 3.4.1 the overlay went dim and lost its frame and motion whenever Cadence wasn't the focused app — which for a click-through overlay is almost always. It's back to full brightness by default, and there's a new Overlay when idle slider under System if you want it to fade while you work.
• Minimal lyric style — the clean Spotify / Musixmatch look: one bold sans, white current line, quiet card. Under Lyric style.
• The ✳ Remix button now follows the gear's hover-only / idle-opacity settings.
