🎨 Palette: Enhanced Welcome Experience & Shortcut Discoverability (#183)

- 💡 What: Upgraded the `kiba-welcome` script to use a structured list
for shortcuts and improved its internal logic. Added the `Meta + D`
(Show Desktop) shortcut and updated Konsole to use the `JetBrains Mono`
font.
- 🎯 Why: Improves discoverability of system shortcuts, provides a more
professional "out-of-the-box" terminal experience, and makes the
onboarding script more robust against UI changes.
- ♿ Accessibility: Improved the readability of the shortcuts guide by
moving from a dense text block to a clear, icon-labeled list.
