[FEATURE]:Allow copying code or file changes from the macOS desktop app conversation history #29913

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

I recently lost some local code due to an accidental error. Fortunately, I noticed that the file changes shown in my previous conversation history within the OpenCode macOS desktop application still preserved my lost code. However, I currently cannot select or copy the code text from the app's chat interface to paste it back into my editor, which is a critical and urgent need in data-loss recovery scenarios.
Describe the solution you'd like
I would love to see a feature that allows users to copy code or file historical diffs directly from the desktop application's chat interface. Specifically:

1.Allow direct text selection and copying ($Cmd + C$) within the message bubbles showing code/file changes.
2.(Optional but awesome) Add a "Copy Code" button at the top-level container of the file change blocks.

Describe alternatives you've considered
Currently, I have to manually re-type the code by looking at the application interface, which is time-consuming and prone to human error when the code snippet is long.

Additional context
This feature would be a lifesaver for developers who accidentally overwrite their files and need to quickly rollback or recover snippets that the AI has previously generated or modified.

Thank you for building such a great tool!
