v0.2.0-alpha.2

Fixed

• Stop presenting a text-only video card when its cover can no longer be
  fetched. Searchy now shows an explicit retry response and does not create a
  Vido download intent for that unusable card.
• Record a grid selection only after its media was sent successfully.
• Remove SepiaSearch from the default discovery pool after a live result linked
  to an unreachable PeerTube instance and timed out in Vido. Bilibili and
  PeerTube remain as the two pinned discovery video engines.
