- Added new attributes for chat colors including rail, date rules, and unread markers. - Enhanced ChatLine class to support colored segments for continuation lines and horizontal separator rules. - Introduced a WelcomeBanner class to display a splash screen when no channel is selected. - Implemented NickColorHelper for deterministic per-nick colors, ensuring consistent user color representation. - Updated ChannelListSource to highlight channels with unread messages and mentions. - Improved MainWindow to include a spinner for transitional connection states and display activity in the status bar. - Added unit tests for NickColorHelper to ensure stable and predictable color indexing.
