研究方向
Review existing ESLint rules in the repository (e.g., in `src/rules/`) to understand the pattern for defining a rule with a `create` function that returns visitors. Use the ESLint AST to detect `ExportNamedDeclaration` nodes with a `source` property, and aggregate exports by source to flag duplicates. Check the issue comments for any discussed edge cases or preferred API. No linked PRs exist, so implement the rule from scratch, ensuring it handles both single and multiple exports from the same source file.
