UI polish: rename Space to Quest, harder examples, clean dropdown, hide progress bar

- README frontmatter title goes from "DeepResearch Space Starter" to
"Quest" so the public Space listing matches the in-app header.
- First two examples are now well-known but detail-heavy questions
(Apollo 11 call signs + lunar surface duration; current 100m men's
world record with the next-fastest legal time).
- Memory Strategy dropdown: flatten the inner .wrap/.container/.single-
select so there's only one outer frame, matching the Model textbox.
- Hide .progress, .progress-level, .progress-bar and .generating on the
Markdown/Code panel — that's the orange bar that was showing up above
"Researching…" while the agent streamed.
