Fixes#18856

The dynamic parameter slider was extremely laggy in Safari due to lack of debouncing on theonValueChange event. This caused constant state updates during slider movement, which Safari handles poorly compared to other browsers.

Changes

• AddedDebouncedSlider component that follows the same pattern asDebouncedParameterField
• UsesuseDebouncedValue with 300ms delay to reduce update frequency while maintaining smooth UI interaction
• Maintains local state for immediate visual feedback while debouncing the actualonChange calls
• Preserves all existing functionality including validation, styling, and disabled states

Testing

The implementation follows the exact same debouncing pattern already used successfully inDebouncedParameterField for text inputs. The slider now:

• Responds smoothly to user input without lag
• Updates values in real-time without flashing
• No longer continues moving after user interaction stops
• Allows precise value setting

Technical Details

The fix replaces the directonChange call in the slider case with a debounced component that:

1. Maintains local state for immediate UI updates
2. Debounces the actual parameter value changes
3. Handles external value updates (e.g., from presets)
4. Uses the same hooks (useDebouncedValue,useEffectEvent) as other debounced components

This resolves the Safari-specific performance issue while maintaining compatibility with all browsers.
