Viper Proxy 0.6.4 — Minecraft 26.1.2

Fixes authenticated SOCKS5 routing for Minecraft server resource-pack downloads. Java's resource-pack HTTP downloader identifies SOCKS credential callbacks as SERVER requests; Viper Proxy now safely accepts that callback only when it matches the active proxy protocol, host, and port. Includes a real JDK SOCKS5 authentication regression test.

Viper Proxy 0.8.2 - Minecraft 26.2 UI Fix

Minecraft 26.2 UI and profile update.

• Fixes the missing-texture magenta/black logo by rendering the standalone PNG as a raw texture instead of an atlas sprite.
• Adds an editable active-profile name field and a dedicated SAVE NAME action.
• Renaming persists without requiring valid proxy host/port and without reconnecting or changing proxy configuration.
• Retains the critical Connection.configureSerialization Mixin hotfix from v0.8.1.
• Verified by clean build, Mixin bytecode checks, profile-rename regression test, packaged-resource inspection, and Minecraft 26.2 startup smoke test.

Supersedes v0.8.1. The Minecraft 26.2 code remains isolated on its dedicated release branch for the later UI overhaul.
