RatioMaster.NET 2.2.0

• Linux AppImages — fix the glibc startup error on Ubuntu 22.04 and preserve portable settings between launches.
• Signed Windows builds — Authenticode signatures and trusted timestamps on x64 and ARM64 downloads.
• Torrent and session reliability — validate cached torrents, reload changed files, and keep counters and saved tabs consistent.
• Tracker robustness — reject malformed responses and ambiguous client profiles; reduce memory use when processing peer lists.
• Interface and activation — prevent actions on closed tabs, respect active-session input locks, and improve single-instance activation.
• Android 17 — handle local-network permissions and cancelled starts while preserving public tracker access when optional LAN access is denied.
• Dependencies — use stable Avalonia 12.1.3 and SkiaSharp 3.119.4 with the official .NET 11 RC1 toolchain; no nightly packages.
• Build organization — centralize generated files under artifacts, keep release packages in Installer/Output, and detect Visual Studio 2026 build tools.
