Adds papaparse as a dependency and updates the data processing service to use it for more robust CSV file parsing. This replaces manual CSV parsing logic with a dedicated library, improving reliability and handling of various CSV formats.
Also renames the `MoversIcon` to `TrendingIcon` to better reflect its usage in indicating trending performance metrics.
Sets up the project with Vite, React, Tailwind CSS, Gemini AI integration, and necessary dependencies for data analysis. Includes initial configuration for TypeScript, Tailwind, and project metadata.
