Version 1.6 - Major Update

New Feature: Per-Tab Control

• Keep-Alive now works on individual tabs instead of globally across all tabs
• Enable/disable the extension independently for each tab
• Extension icon automatically updates to show the correct state for each tab
• Tab states are saved and persist across browser restarts
• Automatic cleanup when tabs are closed

Code Quality Improvements
- Enhanced error handling across all components with better user feedback
- Comprehensive JSDoc documentation for all functions
- Modern async/await patterns replacing promise chains
- Improved code organization with constants and better structure
- Fixed icon references in manifest to use correct files

Accessibility Enhancements
- ARIA attributes added for screen reader support
- Keyboard navigation improvements with proper focus indicators
- Dark mode support via CSS media queries
- Reduced motion support for users with motion sensitivity preferences
- Semantic HTML with proper roles and labels

User Experience Improvements
- Better visual feedback with smooth transitions and hover effects
- Improved status messages showing "Active/Inactive on this tab"
- Button states (disabled during operations to prevent double-clicks)
- Enhanced clock display with "Keep-Alive: [time]" format
- Modern UI styling with system fonts and better color contrast

Performance Optimizations
- Removed unnecessary click event simulation reducing overhead
- Proper cleanup on page unload to prevent memory leaks
- Efficient state management with Map objects
- Automatic re-activation after page reloads

Technical Improvements
- Added activeTab permission for better tab detection
- Improved message validation and error boundaries
- Better handling of tabs without content scripts
- Specified minimum Firefox version (109.0) for compatibility

Breaking Change: The extension now operates per-tab instead of globally. Users will need to enable it separately for each tab they want to keep active.
