chore(adventure-rental-app): strip down application and remove obsolete files

This commit performs a major cleanup of the `adventure-rental-app` by removing all existing components, pages, layouts, and project brief documents. The application is reduced to a minimal Vite shell.

- Deleted all authentication, chatbot, and dashboard components and pages.
- Removed outdated project brief and PRD markdown files.
- Updated Vite and `@vitejs/plugin-react` dependencies.

Additionally, the `framer-motion` dependency was added to the `bookoomoo-app`.
