Added comprehensive selection and editing capabilities to multi-track editor: - Visual selection overlay with Shift+drag interaction on waveforms - Multi-track edit commands (cut, copy, paste, delete, duplicate) - Full keyboard shortcut support (Ctrl+X/C/V/D, Delete, Ctrl+Z/Y) - Complete undo/redo integration via command pattern - Per-track selection state with localStorage persistence - Audio buffer manipulation utilities (extract, insert, delete, duplicate segments) - Toast notifications for all edit operations - Red playhead to distinguish from blue selection overlay All edit operations are fully undoable and integrated with the existing history manager system. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
