v3.9.3

Description

Redesigned the Markdown Viewer workspace around a professional document Explorer, streamlined toolbar, responsive navigation, consistent icon system, and complete interface localization.

• Explorer & Documents: Added workspace, folder, file, favorite, recent-document, secret-workspace, drag-and-drop, multi-selection, context-menu, bulk-delete, and GitHub repository import workflows. Closing tabs remains separate from deleting documents, and repository imports are grouped into repository-named folders with background progress.
• Tabs, Editing & Split View: Added complete tab-closing commands, synchronized two-document split view, compact long-title handling, shared Edit or Preview modes, save-state feedback, and reliable empty-document behavior.
• Toolbar, Icons & Overlays: Reorganized document and formatting actions, standardized dropdowns, introduced a lightweight local Lucide icon subset with consistent 1.5px strokes, refined the empty state, and unified application dialogs and modal accessibility.
• Responsive UI: Replaced the mobile floating menu with a compact workspace drawer, aligned mobile toolbar and tab sizing with desktop, and improved responsive status, settings, and action layouts.
• Localization: Added complete interface catalogs for 14 languages, covering static and dynamic menus, dialogs, Explorer states, progress messages, validation feedback, titles, and accessibility labels while preserving user-authored Markdown and filenames.
• Desktop: Synchronized the Neutralino desktop application with the redesigned web interface and retained seven standalone Linux, macOS, and Windows release targets.
