Pull request overview

Adds an Android stealth no-VPN build mode that swaps out VPN manifest exposure, starts Radiance in local proxy mode, and adjusts Flutter UI to present manual SOCKS5/HTTP CONNECT proxy setup instead of VPN routing controls.

Changes:

• Adds Gradle/Make switches and a no-VPN Android manifest/proguard discard checks.
• Adds Android no-VPN service path and method-channel guards for VPN-only features.
• Adds Flutter build flag, proxy UI, localized labels, and documentation for the new build.
