🐛 Bug Fixes

Badge & Notification Improvements

• Fixed unread count accuracy: Now uses items.length as fallback when API returns unread: 0 but email items exist
• Badge persistence: Badge state now properly persists across service worker restarts
• Improved badge visibility: Added white badge text color for better readability on colored backgrounds

Authentication & Error Handling

• Enhanced auth error detection: Properly distinguishes between:
• First-time setup (shows orange warning badge)
• Token revocation/expiry (shows red error badge)
• Fixed popup behavior: Popup no longer displays cached emails when authentication errors occur
• Notification race condition fix: State is now saved before notification logic to prevent race conditions

Bug fixes and performance improvements.

• Improved notification reliability
• Faster popup loading using cached data
• Better handling of temporary network and authentication errors
• Security hardening and internal code cleanup
