Velo v1.5

### 🆕 What's new in v1.5

🎮 Short notes — release keys as quick, human-like taps instead of holding them, so your note-trails in games (Roblox pianos) look like a real player, not an autoplayer. Random (varied) or fixed timing, tunable in Settings — plus a live preview. Works in the Player, Drums and MIDI → Keys.
🎚️ New "Balanced" Humanize profile — a sweet-spot feel that sits right between Subtle and Moderate.
