AWS amazondynamodb documentation change
Summary
Updated .NET SDK code example from v3 to v4 with improved error handling, added XML documentation comments, null safety checks for pagination, and GitHub example path updates
Security assessment
Changes focus on code quality improvements and SDK version alignment rather than addressing security vulnerabilities. The added exception handling (ResourceNotFoundException, AmazonDynamoDBException) improves error reporting but doesn't directly mitigate security risks. Null safety checks (response?.LastEvaluatedKey) prevent potential null reference exceptions but are general reliability improvements rather than security fixes.
