Pull request overview

This PR migrates the Go proxy implementation out of the main Agent Identity Protocol repository into a dedicated aip-go repository. This refactoring removes all implementation-specific code while maintaining the core specification and documentation in the main repo.

Changes:

• Removes entire implementations/go-proxy/ directory with all Go implementation code, tests, documentation, and examples
• Updates README.md to add a new "SDKs & Implementations" section pointing to the external aip-go repository
• Adds a reference link to the Go implementation at the top of the README
