Go 1.27

Go 1.27 introduces major language enhancements including generic methods, improved struct literal initialization for nested fields, and generalized function type inference that eliminates the need for explicit type arguments in many contexts. The release also includes toolchain improvements such as new modernizers in `go fix` and package version queries in `go doc`, plus runtime optimizations that reduce small object allocation costs by up to 30%. New standard library additions include `encoding/json/v2` for high-level JSON processing, `crypto/mldsa` for post-quantum cryptography, and `uuid` for native UUID support.
