SpoofGUI v1.0.3

Fourth release for the Windows client built on SNI-Spoofing to make the usage easy and fast! This release moves from just a client to a client with its own modified, faster SNI-Spoof core, plus DNS control, real-delay testing, and a curated SNI list.

What's New:

• Faster, tougher SNI core — rebuilt the engine relay (adapted from atarevals/SNI-Spoofing): a single dropped connection no longer kills the engine, and the Windows log spam is gone
• Added Fast mode — low-latency engine sockets (TCP_NODELAY + small buffers) for gaming / real-time; toggle it in Settings
• Added DNS control — set Remote, Direct, and Bootstrap DNS servers + a resolution strategy (used in Tunnel mode), just like v2rayN
• Fixed TUN + LAN sharing — private / LAN ranges now bypass the tunnel, so phones/devices can reach the PC's listener over the LAN while Tunnel mode is on
• Up to 100 profiles + Fetch from repo — pull a curated sni.json list straight from GitHub and bulk-create profiles
• Ping (real delay) — test one config (right-click) or ping all at once; right-click also exports a config to the clipboard
• Added vless + xhttp / httpupgrade transport support
• Faster startup + splash screen — instant loading window while the app starts; ReadyToRun-compiled release builds
• Cleaner uninstall — Setup now removes the whole app folder on uninstall
