desktop: Cmd+A does not select chat messages for copy-paste

Description

In the desktop app on macOS, hitting Cmd+A and then Cmd+C does not let you copy the chat history.

The prompt input box constantly holds focus, so pressing Cmd+A only highlights text sitting in the prompt box. Even if you click up into the chat timeline, the root layout container has selection disabled (select-none), so you can't select the conversation text with the keyboard.

Right now, copying anything from the chat means manually dragging the mouse all the way from the bottom up. That's pretty clunky, and because the timeline is virtualized, dragging doesn't even pick up messages that have scrolled off-screen.

In Claude Code, Codex, and standard chat UIs, doing Cmd+A -> Cmd+C (or using a copy transcript shortcut) just works. In OpenCode Desktop, there doesn't seem to be a way to copy the conversation without dragging.

Steps to reproduce

1. Open OpenCode Desktop on macOS and run a chat session with several messages.
2. Hit Cmd+A (or click inside the chat messages and hit Cmd+A).
3. Notice only the prompt input gets selected (or nothing in the chat gets selected).
4. Hit Cmd+C — the conversation is not on the clipboard.
5. The only way to copy text is manually clicking and dragging the mouse up across visible messages.
