v1.4.0

• Breaking: Replace string icon names, IconName and the monolithic icon_data registry with 800+ named IconData exports from svelte-widgets/icons; pass imported glyph values directly to Icon and icon-bearing component props. The expanded Iconify-backed catalog now tree-shakes unused glyphs. A one-icon Vite 8.2 production bundle drops from 57.5 kB minified / 20.0 kB gzip to 0.3 kB / 0.2 kB (98.9% smaller gzipped) #440
• Breaking: Standardize public numeric timing props on milliseconds with an _ms suffix. Rename CopyButton.reset_sec to reset_ms and Toc.flashClickedHeadingsFor to flash_clicked_headings_for_ms; append _ms to CommandMenu.fade_duration, Masonry.duration, Nav.dropdown_cooldown, Popover.open_delay/close_delay, TooltipOptions.delay/hide_delay and Wiggle.duration #441
• Add a searchable gallery for the full icon catalog; click any glyph to copy its svelte-widgets/icons import #440
• Add generic ActionButton with pending, success and error feedback, typed results, bindable state and reset timing; CopyButton now composes it #440
• Keep svelte-widgets/vite-config types structural across separate Vite+ installations, and make CopyButton button hosts explicit type="button" elements with a styleable data-state #440
