New
- Optional sound alert: get a short chime when a new Fiverr message or
notification arrives. Turn it on/off and set the volume from the toolbar popup.

Fixed
- The red tab icon works again. Notification detection was rebuilt for Fiverr's
redesigned header.

Improved
- Rebuilt on Manifest V3 and removed jQuery — lighter, faster, and ready for
current Chrome and Firefox.
- Added a short "what's new" page on install and major updates.
