✨ Enhanced ControlXY UI & Nested Sequences - Implementation Complete!

🎉 What's New

1. Nested Sequences - Patterns of Patterns!

Create meta-sequences that reference other sequences using seq: prefix.

2. Tabbed UI - Three organized tabs

• Presets tab - Save, quick save (9-button grid), recall
• Sequences tab - Create, play, shows nested indicator 🔗
• Generators tab - Pattern generation with auto-play

3. Quick Save - 9-button position grid (↖↑↗←⊙→↙↓↘)

🚀 Quick Test (30 seconds)

// Open UI
// Press Alt+Shift+P

// Or via console:

// Test nested sequences:
window.controlXYPresets.defineSequence('a', ['left', 'right']);
window.controlXYPresets.defineSequence('b', ['top', 'bottom']);
window.controlXYPresets.defineSequence('meta', ['seq:a', 'seq:b']);
window.controlXYPresets.playSequence('meta', { dur: 1, loop: true });
