Function searchValidatorDirectUsage

searchValidatorDirectUsage(node: SgNode): SgNode<TypesMap, Kinds<TypesMap>>[]
Inspect the validator direct usage code snippets. A member expression calling the ".validate" method is considered as direct usage of the validator.

This function specifically looks for patterns where validators are called directly with the .validate() method, which is common in AdonisJS applications.
Parameters
- node: SgNode
  The AST node to search within for validator direct usage
Returns SgNode<TypesMap, Kinds<TypesMap>>[]
Array of SgNodes representing validator expressions that call validate method
Example
```
const methodNode = classNode.find({ rule: { kind: 'method_definition' } })
const validators = searchValidatorDirectUsage(methodNode)
validators.forEach(validator => {
  console.log('Direct validator usage:', nodeToPlainText(validator))
})
```
