v2.0.0-alpha.3

Bug Fixes

mergeProps utility improvements

• Preserve base className when override is falsy (null, undefined, empty string)
• Preserve base event handler when override is null or undefined
• Only merge React event handlers (onClick, onMouseDown, etc.) — props like onboarding, ongoing are no longer incorrectly merged as event handlers
