feat: Undo/Redo + Main Menu + Global Settings + Global EQ
- Undo/Redo in header bar: snapshot-based tracking for block adds, removes, reorders, parameter changes, and model swaps. 50-level undo stack with debounced param snapshots (400ms cooldown). - Main Menu: slide-out sidebar from left with ☰ button in status bar. Items: Save Preset, Bypass/Control, Global Settings, Global EQ, Tuner, Wi-Fi / Bluetooth. - Global Settings: full-screen overlay with grouped settings — Audio (Master Volume, Input Pad, Impedance), MIDI (Channel, Clock, Thru), Display (Brightness, Auto Dim, Screen Saver), Tempo (Tap Tempo, Division, Mute). - Global EQ: 3-band shelving equalizer (Low 80Hz, Mid 800Hz, High 6.4kHz) with large knobs, canvas-based frequency response graph, and reset button. - New files: src/MainMenu.jsx, src/GlobalSettings.jsx, src/GlobalEQ.jsx
