Summary
This PR adds S3 bucket browsing functionality to the TUI with bucket listing, prefix-style object navigation, and object detail views. The implementation is well-structured with proper separation of concerns and consistent patterns.
Critical Issues
Crash Risk (Must Fix): The ListBuckets function has a critical error handling issue where a single bucket region lookup failure causes the entire operation to fail. This prevents users from viewing any buckets if they lack permissions or encounter transient errors on even one bucket. The error should be handled gracefully by logging and using a fallback region value.
Code Quality
The code follows the existing patterns in the codebase and includes:
- Proper error handling in most areas
- Consistent naming conventions
- Well-organized UI code with filtering support
- Clean model structures and helper functions
Test coverage appears comprehensive with tests for the service, catalog, app, and AWS repository layers.

Summary
This PR successfully adds an S3 bucket browser feature to the TUI with comprehensive functionality for listing buckets, browsing objects with prefix-based navigation, and viewing object details. The implementation follows established patterns in the codebase and includes proper test coverage.
Changes Reviewed
- ✅ New S3 service layer with ListBuckets, ListBucketObjects, and HeadBucketObject methods
- ✅ TUI screens for bucket list, object list, and object detail views
- ✅ Filtering support for both buckets and objects
- ✅ Breadcrumb navigation for S3 prefixes
- ✅ Comprehensive unit tests for S3 functionality
- ✅ Proper integration with existing AWS repository structure
Critical Issue Found
One logic error was identified regarding error handling in the bucket region lookup that could mask permission or configuration issues. Please review the inline comment for details.
The implementation is otherwise solid and ready for merge once the error handling concern is addressed.

🛑 Logic Error: Missing nil check on returned error from bucketRegion creates potential for misleading error messages. When GetBucketLocation fails (e.g., due to permission denied or cross-region access restrictions), the error is logged but the region is set to "unknown" and execution continues. However, if multiple buckets fail, the actual error details are lost, making it difficult to diagnose the root cause. The logic should distinguish between non-fatal errors (where "unknown" is acceptable) and fatal errors that should stop execution.

This PR adds a well-implemented S3 browser feature with good error handling and comprehensive test coverage. The code demonstrates solid engineering practices including graceful handling of non-fatal errors (like inaccessible bucket regions), thorough unit tests, and proper bounds checking in UI navigation.
Critical Finding:
One logic issue identified: Assignment to value receiver method parameter m.awsRepo at line 59 in screen_s3.go modifies a copy rather than the original, causing the repository to be recreated on every call. While the code will function, this creates inefficiency through repeated AWS client initialization.
Strengths:
The implementation shows attention to detail with sorted outputs, defensive programming in array access, good separation of concerns, and appropriate test scenarios including edge cases. The S3 prefix navigation logic is clean and handles the virtual folder structure correctly.
Overall, this is a solid feature addition with one optimization opportunity.
