Fixed: you no longer get signed out every time you restart your browser. Your
login was never actually lost — the popup was misreading a slow or unavailable
network as a sign-out, so re-entering your password looked like the only fix.

Added: the extension now keeps your session fresh in the background, so the
popup opens already signed in instead of waiting on the network.

Fixed: signing out of the extension no longer signs you out of the YjTracker
web app or your other devices.

New: when the network is unreachable you now get a "Can't reach YjTracker"
screen with a Retry button, instead of a login form for a session that is
still perfectly valid.

Updated the name and logo to match the app (YjTracker).
