feat(ux): rename creativity levels with descriptive labels and inline descriptions

- "Use What I Have" / "Allow Swaps" / "Get Creative" / "Surprise Me 🎲"
- Active level shows a one-liner description beneath the selector
- Hover tooltips repeat the description for mouse users
- Label changed from "Creativity Level" to "How far should we stretch?"
- Wildcard confirmation copy updated to match new framing
