Go 1.27 adds generic methods (golang/go#77273). golang.org/x/tools go/ssa v0.42.0 does not instantiate them: objectMethod only applies receiverTypeArgs and ignores method-level type parameters, so a call such as (*math/rand/v2.Rand).N resolves to the abstract generic method and its body reaches createConst with a type-parameter-typed zero constant, triggering "panic: expected nil interface constant". Upgrade golang.org/x/tools to v0.47.0, whose go/ssa returns nil from MethodValue for generic methods and instantiates method-level type parameters. No compiler changes are required. Since x/tools v0.47.0 requires Go 1.25, raise the minimum supported Go version from 1.24 to 1.25. Signed-off-by: deadprogram <ron@hybridgroup.com>
