chore: rename xaionaro-go -> AndroidGoLab across all files

Project moved to github.com/AndroidGoLab/ndk. Updated all import
paths, URLs, and references in Go files, YAML specs/overlays,
README.md, go.mod, templates, and tests. Also updates jni and
binder references to their new AndroidGoLab locations.
