✅ PROGRESS TRACKING IMPROVEMENTS:
• Added two-layer progress tracking for zip operations:
- Collection progress: 'Processing file X of Y' with percentage
- Individual file progress: Current file compression with bytes processed
• Enhanced collection progress messages with file counters
• Added overall progress percentage calculation based on file count
• Improved progress status messages with speed information
✅ DEPENDENCY OPTIMIZATION:
• Removed redundant Newtonsoft.Json.dll (not used in codebase)
• Only System.Text.Json.dll is needed and used for JSON operations
• Updated module manifest to reflect minimal dependencies
• Reduced module footprint and eliminated unused dependencies
✅ TECHNICAL IMPROVEMENTS:
• Added _totalFiles field to track collection size
• Enhanced progress calculation logic for better user experience
• Maintained existing progress event structure for compatibility
• Fixed CompressedLength access timing issue in previous commit
Now zip operations show proper 'Processing file 3 of 10' style progress
with both collection and individual file progress bars.
� BUG FIX:
• Fixed InvalidOperationException: 'Length properties are unavailable once an entry has been opened for writing'
• Added try-catch block around entry.CompressedLength access
• Use uncompressed size as fallback when CompressedLength is not available
• Ensures zip operations complete successfully without errors
✅ SOLUTION:
• CompressedLength property is only available after entry stream is fully closed
• Added graceful fallback to prevent operation failures
• Maintains accurate progress reporting and metrics collection
• Preserves all zip functionality while fixing the access timing issue
The zip archive creation now works reliably for all file types and sizes.

- Simplified error handling to show only essential information:
* Operation, Message, ExceptionType, InnerExceptionType, InnerExceptionMessage
* Removed system info, stack traces, and operation details for cleaner output
- Started enhancing New-MinIOObject cmdlet with parameter sets:
* SingleFile: Original single file upload functionality
* Files: FileInfo[] support for multiple file uploads
* Directory: DirectoryInfo support with recursive options
- Added new parameters for enhanced functionality:
* BucketDirectory for organizing uploads into nested structures
* Recursive, MaxDepth, Flatten for directory uploads
* InclusionFilter, ExclusionFilter for file filtering
* Force parameter for overwriting existing objects
Next: Complete the parameter set implementation and add multi-layer progress tracking.
