v0.4.3

Changed

• Tray menu now shows server URL and hub peer count as disabled
  info lines below the status item. Linux tray icons (libayatana-
  appindicator) don't support tooltips, so the server address and
  hub connection count are now always visible in the right-click
  menu. The tooltip is still maintained for platforms that support it.
• Smaller status-dot overlay on the tray icon. Reduced from ~35%
  to ~22% of the icon side so the actual icon artwork is more
  visible while the colored connection-status dot still reads clearly.
