chore: Bump version to v0.3.1

Update screenshot in README.md

Replaced an image link with a new screenshot link.

fix: use correct macOS API for systray icon title updates (#128)

- Use NSStatusItem.button property for set_title() instead of calling
  NSButton::setTitle_ directly on the NSStatusItem object
- Fix set_menu_item_title() to use msg_send![item, setTitle:] instead
  of NSButton::setTitle_ on NSMenuItem
- Fix initial title setup in SystemTray::new() same way
- Log errors on UPDATE_UI command submission failure instead of
  silently discarding with _ =
