Revamp CSV library marketing for database workflows
Updated csv.html and csv-social.html to emphasize database-first features, native IDataReader support, and progress reporting. Revised performance benchmarks, feature highlights, and comparison sections to target database professionals and clarify advantages over raw parsing libraries. Updated links and version references to reflect latest release.
