SOCKS5 Proxy Support Infrastructure Added

What: Linux network bridge now supports both HTTP and SOCKS5 proxy ports for future sandbox use.

Details:

• Function gBB() at line 375277 now accepts both HTTP and SOCKS proxy port parameters
• Returns both httpProxyPort and socksProxyPort in the bridge configuration (lines 375327-375328)
• Environment variables configured for gRPC, Docker, and Cloud SDK to use SOCKS proxies
• Infrastructure is in place but not active due to sandbox being disabled
• Evidence: gBB() signature changed from (A) to (A, B) at line 375277, with new return structure including both ports

Note: This enhancement will only be effective when the sandbox system is re-enabled.
