- Replace generic dialog content with custom panel layout
- Add animated GO block logo reusing the existing opencode logo
shimmer/click-burst system via a new shape prop on Logo
- Add idle shimmer mode: continuous tight white specular highlight
traveling across lit letter pixels only (shadow cells excluded)
- Add BgPulse component: radial primary-tinted rings emanating from
the GO center, phase-synced with the logo shimmer so rings emit
exactly when the shine reaches the center of GO
- Pixel-accurate centering via refs on the logo box
- Buttons reordered: 'don't show again' bottom-left, 'subscribe'
bottom-right and default-selected
