Add Lucide icon library and switch many inline SVGs to programmatically generated Lucide icons for consistent styling and reuse. Adds frontend/vendor/lucide.min.js and includes it in index.html; adds helper functions (escapeSvgAttr, svgAttrs, lucideIcon) in app.js and replaces numerous hard-coded SVG strings with Lucide-generated icons and CSS utility classes. Update components.css with .gd-lucide-icon, color helpers for folder/file icons, and remove a global stroke-width override so icon strokeWidth can be controlled per icon. Small accessibility and UI tweaks: use aria-label/title on several buttons and swap icons in modals, menus and toolbars. Also updates package.json/package-lock.json (dependency adjustments).
