feat: implement native Rust audio with Winamp-inspired media console
- Replace mpv dependency with rodio for cross-platform audio - Add Winamp-style media console with real-time controls - Implement vim-style keybindings (hjkl navigation, space pause) - Add Unix-style progress display and tmux-inspired status line - Support HTTP streaming for podcast playback - Real-time volume control and position tracking - Remove debug output that interfered with TUI 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
