v1.0.0-beta.1

What's new

• Session verification, rebuilt. Emoji and QR flows no longer hang, requests
  from your other devices are answered instead of dropped, and a cancellation
  says whether it was a security mismatch or just a timeout.
• Emoji render in message text — blank on Linux and mismatched on Windows
  before, now the same artwork everywhere.
• A deleted session signs you out instead of retrying forever behind
  "Waiting for network…".

Fixes

• Messages stuck on a glowing "unable to decrypt" bubble after verifying a
  new device now decrypt on their own.
• The unread counter and "unread messages" line could both be wrong on a
  fresh login.
• Clicking a notification keeps the room live, so it still marks read and
  shows new messages.
• Signing in after signing out failed on Windows until you restarted.
