refactor(lint): consolidate inspection error handling

- Removed `PsiErrorCollector` and `PsiSyntaxCheckingVisitor` as they are no longer needed.
- Introduced `SketchInspectionError` in a separate file to centralize error handling logic.
- Cleaned up and reorganized related code in `SketchCodeInspection` for better readability.
