- Introduced modularity by splitting Beam into new projects: Beam.Abstractions, Beam.Models, and Beam.Downloaders. - Refactored existing classes into appropriate namespaces and projects. - Replaced specific implementations with abstractions (e.g., SourceLinkBuilder to LinkBuilder, State to IState, etc.). - Updated interfaces: added ITemplate, IArticleData, IDownloadReport, and others for improved extensibility. - Removed deprecated classes like SourceLinkBuilder and StateChangerFactory. - Enhanced link handling in downloaders by refactoring to use `string` over `SourceLink`. - Consolidated shared logic under Beam.Abstractions.
