TypeError: e.diffs.map is not a function when reopening old browser session

Bug Description

When trying to reopen an old OpenCode web browser window, I get the following JavaScript error:

TypeError: e.diffs.map is not a function
    at Object.fn (http://localhost:4096/assets/session-BdJIdAn0.js:19:50326)

Steps to Reproduce

1. Open OpenCode web interface
2. Try to reopen an old browser session/window

Environment

• OpenCode version: 1.2.27
• Browser: Happens in Brave, Chrome, Edge
• OS: Windows 11

Additional Context

The error suggests that e.diffs is not an array (or is undefined) when the map function is called. This may be related to session state corruption or an issue with how session data is being deserialized.

I’ve encountered this issue as well. I’m currently on the latest version (1.3.2), and the error persists even after switching computers or browsers; the only time it stops is when I switch to the mobile version.
