Release v1.0.2: tour, quiz & UI fixes

Bump version to 1.0.2 and add changelog. Update 3D tour behavior so clicking a different planet moves the camera (set index) while clicking the current planet opens its detail view. Lock quiz flow: answers are frozen on selection, options are disabled after answering, and the Previous button has been removed to enforce one-way progression. Improve mobile scroll stability by adding touch-action: none and will-change: transform to the intro/Earth canvas. Remove the development-only planet-test page and clean up .gitignore entries. Update README copy and badges to reflect the release and feature changes.

+## Changelog
+
+### 1.0.2
+- **Planet navigation:** Clicking a planet you are not currently on in the 3D tour now travels the camera directly to that planet rather than opening its detail page. Clicking your current planet still opens the detail view.
+- **Quiz integrity:** Quiz answers are locked immediately on selection. The Previous button has been removed — quiz flow is strictly one-way to prevent score manipulation.
+- **Mobile scroll stability:** Fixed jitter/stutter of the Earth animation on the home screen when scrolling on mobile by adding `touch-action: none` to the intro container and promoting the Earth canvas to its own GPU compositor layer.
+- **Cleanup:** Removed the development-only planet test page (`/planet-test`). No sensitive data or secrets found in the repository; `.gitignore` coverage verified.
