Update hero title and hide stray orange line above tab panel

- New title: "Quest: A Fully Open Recipe for Training Deep Research
Agents from Scratch".
- Zero out any border-top / ::before on .tabitem/.tab-content so Gradio
no longer paints a thick accent bar above the Result panel during a
streaming run.
