- Fix pianoroll/sequencer Transport not resetting on stop/restart (notes
were scheduled in the past and never fired)
- Stop and cancel Transport in stopAudio() to prevent stale events
- Add zoom +/- buttons to scope widget (6 levels, 64–2048 samples)
- Increase scope analyser buffer from 256 to 2048 for wider time view
- Add vertical grid lines to scope display
- Add "Limpiar" clear canvas button to PuzzleView
- Skip audio-graph connection for keyboard/seq/pianoroll freq→osc freq
(direct frequency setting prevents inaudible ultrasonic values)
- Auto-trigger envelopes without gate connections for noise/ambient levels
