🎨 Palette: Add tooltips to README images

[google-labs-jules]

💡 What: Added title attributes to the social media and skills badges in the README.md file.
🎯 Why: This provides helpful tooltips on hover, creating a more consistent and polished user experience, as other images in the README already had this feature.
📸 Before/After: Not applicable for a non-visual change like this, but the result is that tooltips now appear on hover for the affected images.
♿ Accessibility: While alt text provides screen reader information, the title attribute adds a layer of context for sighted users via tooltips, improving the overall usability of the document.

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!
