Add Algorithm Animation Controls

# Add Algorithm Animation Controls

**Priority:** Medium

## Description
Users need more control over the algorithm visualization process. Current step-by-step implementation lacks flexibility and control options.

## Proposed Features
1. Playback Controls:
- [ ] Play/Pause button
- [ ] Step forward/backward buttons
- [ ] Animation speed slider
- [ ] Reset button

2. Timeline Features:
- [ ] Progress indicator
- [ ] Clickable timeline for direct navigation
- [ ] Step count display
- [ ] Current state indicator

3. Visualization Options:
- [ ] Toggle node highlighting
- [ ] Path trace animation
- [ ] Distance label visibility toggle
- [ ] Animation style selection

## Implementation Notes
- Use RequestAnimationFrame for smooth animations
- Store algorithm states for backward navigation
- Implement animation queue system
- Add keyboard shortcuts for controls

## Technical Requirements
- Animation frame rate: 60 FPS
- Smooth transitions between states
- Memory-efficient state management
- Responsive control panel layout

## Acceptance Criteria
- All controls should work without glitches
- Animations should be smooth
- User should be able to navigate to any step
- Controls should be intuitive
