fix(template-require-input-type): JSDoc comment + is-native-element sync (Copilot review)

- Update the in-rule comment: isNativeElement checks 'bindings in the scope
  chain', not 'scope references' — the implementation walks scope.variables
  up scope.upper.
- Byte-identical sync of lib/utils/is-native-element.js to PR #50 canonical;
  drops the stale template-no-noninteractive-tabindex JSDoc reference.
