Go Analysis Framework: modular static analysis by go team

# Summary The Go Analysis Framework is a modular static analysis system that allows developers to create and integrate code checkers (analyzers) that inspect Go packages for errors and issues. Analyzers implement a common `Analyzer` interface, enabling them to save information from lower-level packages and reuse it when analyzing higher-level packages, allowing for flexible integration into various tools like vet, IDEs, build systems, and code review platforms. The framework simplifies the creation and deployment of custom static analysis tools by providing a standardized approach to defining analyzer logic, flags, and interdependencies.
