研究方向

Implement a new rule in SwiftLint that detects empty extensions (extensions with no members). Look at existing rules like EmptyEnumRule for reference. The AST for an extension is represented by the `ExtensionDecl` node; check its `members` array for any declarations. Consider edge cases such as extensions with attributes or conditional compilation blocks. Since the issue has an assignee, coordinate with them before starting work.
