Modern TUI with Enhanced Protocol Hierarchy Interface

Major Features:
- Complete modern TUI interface with three focused views
- Enhanced multi-column layout: Source | Proto | Destination | Extended | Frame Type | Metrics
- Simplified navigation with 1/2/3 hotkeys instead of F1/F2/F3
- Protocol hierarchy: Transport (TCP/UDP) → Extended (CH10/PTP) → Frame Types
- Classic TUI preserved with --classic flag

Views Implemented:
1. Flow Analysis View: Enhanced multi-column flow overview with protocol detection
2. Packet Decoder View: Three-panel deep inspection (Flows | Frames | Fields)
3. Statistical Analysis View: Four analysis modes with timing and quality metrics

Technical Improvements:
- Left-aligned text columns with IP:port precision
- Transport protocol separation from extended protocols
- Frame type identification (CH10-Data, TMATS, PTP Sync)
- Cross-view communication with persistent flow selection
- Context-sensitive help and status bars
- Comprehensive error handling with console fallback
