build failure with Go 1.25

[katexochen]

I'm getting a build failure when trying to build gobusybox with Go 1.25:

 vendor/golang.org/x/tools/internal/tokeninternal/tokeninternal.go:78:9: invalid array length -delta * delta (constant -256 of type int64)

Readme says supported Go versions are 1.20-1.22, but those are EOL.
