The analytics manager has been significantly refactored to allow the use of multiple providers simultaneously. The API has been adjusted, replacing the single active service with a new Map called activeServices, to hold the active analytics services. Additionally, several methods have been modified to return promises rather than void. The 'defaultProvider' property has been removed, as it no longer fits into the system architecture.
* Add Analytics package
Created a new analytics package with a manager to handle tracking of events and page views. The package includes a default provider that can be switched out and uses a NullAnalyticsService if no provider is registered. Additional types, scripts, and package configuration are also provided to support development.
* Add marketing components for UI package
Introduced new React components under "marketing" for the UI package. These include 'Pill', 'GradientSecondaryText', 'Hero', 'CtaButton', 'FeatureCard', 'FeatureGrid', 'FeatureShowcase', 'GradientText', 'Header', and 'SecondaryHero'. Updated 'package.json' to export these components. Replaced the implementation of 'Home', 'SiteHeader', and 'SiteFooter' with these components for cleaner code and better reusability.
