[Bug] OpenCode Web shows "No folders found" although projects are returned by the backend API

Description

When running opencode web, the Web UI starts successfully and is accessible in the browser.

However, the home page and the Open Project dialog both show "No folders found", even though the backend already returns all projects correctly.

The issue appears to be on the Web UI side because:

• /project returns all existing projects (17 projects in my case)
• /session returns existing sessions
• All requests return HTTP 200
• The UI still shows an empty project list

Server log also prints:

Failed to initialize fff
Failed to init file picker: Can not run certain FFF features in a file system root or home directories. Consider smaller per-project directories.

### Additional information

The backend appears to work correctly.

`GET /project` returns existing projects, for example:

```json
[
  {
    "worktree": "/Users/.../Documents/GitHub/openclaw"
  },
  {
    "worktree": "/Users/.../Documents/GitHub/unified-agentic-os"
  }
]

The local database also contains projects:

SELECT COUNT(*) FROM project;
17

The issue seems to be that the Web UI does not render the projects even though they are successfully returned by the backend.
