Full Release Notes

### Added
- **Windows Process Identification**: Implemented full process lookup using Windows IP Helper API
  - Uses GetExtendedTcpTable and GetExtendedUdpTable for connection-to-process mapping
  - Resolves process names via OpenProcess and QueryFullProcessImageNameW
  - Supports both TCP/UDP and IPv4/IPv6 connections
  - Implements time-based caching with 2-second TTL for performance
  - Migrated from winapi to windows crate (v0.59) for better maintainability
- **Privilege Detection**: Pre-flight privilege checking before network interface access
  - Detects insufficient privileges on Linux, macOS, and Windows
  - Provides platform-specific instructions (sudo, setcap, Docker flags)
  - Shows errors before TUI initialization for better visibility
  - Detects container environments with Docker-specific guidance

### Fixed
- **Packet Length Calculation**: Use actual packet length from IP headers instead of captured length
  - Extracts Total Length field from IP headers for accurate byte counting
  - Fixes severe undercounting for large packets (NFS, jumbo frames)
  - Resolves issues with snaplen-limited capture buffers

### Changed
- **Documentation**: Updated ROADMAP.md and README.md with Windows process identification status and Arch Linux installation instructions
