v0.2.8

Fixed

• the observer now works on displays with unusual screen resolutions. some virtual
  machines and monitor modes use sizes that previously showed a "screen" source error;
  solstone now handles them automatically.
• the observer no longer flickers its status when your screen is still. a static
  screen — reading, watching, or stepped away — now stays "observing" instead of
  flipping to "starting."

Changed

• setup now installs Microsoft's WebView2 runtime for you when it is missing, so
  solstone opens on a clean or minimal windows install without a manual step. most
  machines already have it and see no change.
