v3.4.0

Maple 3.4.0 brings the new encrypted Transport V2 client, queued chat follow-ups,
and improvements to Agent Mode and account management.

• Queue follow-up messages while a chat response is running, then edit or remove
  them before they send. Attachments, model choices, and web-search settings stay
  with each queued message.
• Updated encrypted sessions and sign-in flows, including native account
  confirmation and session-bound browser handoffs.
• Use the Quick/Powerful model selector in Agent Mode, with improved handling of
  inference capacity limits.
• Upgrade eligible Bitcoin-paid plans through the app and review subscription
  guidance before deleting a paid account.
• Updated available models and dependencies.

Existing users will need to sign in again after the Transport V2 upgrade.
The release includes Maple SDK 4.0.0 and Maple Proxy 0.4.0.
