ArasClient v1.3.4 — Premium menu & .arasc v2

🎨 New menu design

• Rebuilt the main menu to a premium, hierarchical layout: big ArasClient header card with arrow, MANAGE / FILES & TOOLS / SYSTEM sections, three equal tile cards each (icon + title + description), full-width About card and subtle footer buttons

📦 Richer exports

• Export whole subscriptions (URLs + update settings) — optionally, with one switch
• Message to receiver: exporters can attach a note that shows to whoever imports the file (like NPV), fully encrypted

✨ Polish

• First-run setup now asks about auto-scroll, auto-sort and subscription messages
• Update dialog renders changelogs cleanly (headers, bullets, bold — no raw markdown mess)
