Major update: Enhanced documentation, comprehensive examples, and fixed remaining issues

- Updated README.md with modern feature descriptions and comprehensive overview
- Enhanced docs/USAGE.md with advanced object listing, directory management, and chunked operations
- Created examples/ directory with 6 comprehensive example scripts:
  * 01-Basic-Operations.ps1 - Fundamental operations for beginners
  * 02-Advanced-Object-Listing.ps1 - Filtering, sorting, and pagination
  * 03-Directory-Management.ps1 - Nested directory structures and organization
  * 04-Chunked-Operations.ps1 - Large file handling with performance optimization
  * 05-Bulk-Operations.ps1 - Batch processing and automation workflows
  * 06-Enterprise-Automation.ps1 - Enterprise monitoring, reporting, and compliance
- Added comprehensive examples/README.md with usage patterns and best practices
- Fixed directory creation warnings (now clean verbose logging)
- Implemented missing Get-MinIOObject cmdlet with full filtering/sorting capabilities
- Added timing and performance metrics to all operations
- Enhanced chunked operations with multi-layer progress tracking
- Improved error handling and resource cleanup
- Removed temporary test files and cleaned up repository structure
- All examples use proper PowerShell output (no Write-Host usage)
- Professional logging with timestamps and structured output
