feat: implement advanced VPN routing and application filtering
- Optimize core proxy to skip MITM when SNI is unchanged - Add Whitelist/Blacklist application filtering modes - Create high-performance AppWhitelistScreen with search and system app filter - Implement Bypass LAN, Strict DoH, and IPv6 Blocking features - Reorganize Settings UI with an Advanced settings group - Fix MTU setting with a specialized dialog and numeric input - Update default DoH nameservers to remove Google DNS - Add QUERY_ALL_PACKAGES permission for accurate app listing
