fix: resolve gesture handler worklet conflicts and enhance color support

[mmestiyak]

🎯 Problem

This PR addresses critical issues that prevented the library from working properly with React Native Reanimated and Gesture Handler:

1. Worklet Conflicts: Mixed worklet/non-worklet callbacks caused react-native-gesture-handler errors
2. Limited Color Support: Named colors ("red", "blue") and various hex formats didn't work with alpha transparency
3. Expo SDK Compatibility: Peer dependency requirements were too strict for broader Expo SDK support

🔧 Solution

Worklet Resolution

• Added .runOnJS(true) to Gesture.Pan() chain to force all callbacks to JavaScript thread
• Removed all 'worklet' directives and runOnJS() wrappers from gesture handlers
• Pre-computed color values outside worklet context to prevent synchronous UI thread calls

Enhanced Color Support

• Integrated color-alpha library for robust color handling
• Added support for named colors ("red", "blue", "green", etc.)
• Enhanced hex code support (3-digit, 6-digit, with/without #)
• Proper alpha transparency handling for all color formats

📦 Dependencies

• Added: color-alpha for robust color manipulation
• Updated: Peer dependency requirements for broader compatibility

📝 Example Usage

<Joystick
  size={150}
  color="red"  // ✨ Named colors now work!
  onMove={(data) => {
    // ✨ No more worklet errors!
    console.log('Position:', data.position);
    updateState(data.position);
  }}
/>
