feat: polish home page UI -- card borders, colored icons, 3-col grid, Cmd+K hint

- Tool cards: subtle border, modality-colored icon backgrounds, better hover
- Category headers: bottom border separator for visual structure
- Grid: 3 columns on lg screens instead of 2
- Search bar: Cmd+K keyboard shortcut hint, tighter styling
- Tabs: softer styling, count separated from label
- Recent pills: subtler border style instead of bright orange
- Tighter vertical spacing throughout
- Wider max-width (max-w-6xl) for better use of screen space
