Progress Reporting and Status Updates*

Difficulty: ⭐⭐⭐ (Medium)
Dependencies: Issue #15
Component: CLI Interface

Description: Implement comprehensive progress reporting for long-running operations to keep users informed and enable better monitoring. Add interactive progress bars for scanning operations that show percentage completion and current activity, implement real-time status updates that stream to the console as operations progress showing discovered services and any errors, and add robust operation cancellation support that allows users to gracefully interrupt scans with proper cleanup. Support verbose progress reporting mode that provides detailed information about each step for debugging purposes, add operation time estimation based on historical performance data and current progress, and implement progress persistence that saves state to allow resuming interrupted operations. Include progress callbacks for programmatic access to progress information, add progress aggregation for multi-cluster operations showing overall and per-cluster progress, and support different progress output styles (simple, detailed, machine-readable).

Acceptance Criteria:

• Add progress bars for scanning operations with indicators
• Implement real-time status updates with timestamps
• Add operation cancellation support with signal handling
• Support verbose progress reporting mode
• Add operation time estimation with ETA
• Implement progress persistence for resumption
