Update the multiselect guide and all 27 interactive examples to utilize the modern standalone, Signal-based Angular ARIA APIs. * Modernize all examples (Standard, Material, Retro) to use standalone directives, animations, and focus suppression. * Update the multiselect guide API tables and templates: - Document ngComboboxPopup, cdkConnectedOverlay, and disabled input. - Document ngListbox selectionMode, focusMode, tabIndex, and value signal. - Document activeDescendant active focus tracking with ngComboboxWidget.
Remove the delayed overlayOpen signals and synchronization effects across all 9 multiselect example variations. Bind cdkConnectedOverlayOpen directly to popupExpanded() and remove conditional closing classes to simplify code.
