TUI logs 'Failed to read KV state' ENOENT error on fresh install

Description

On a device where ~/.local/state/opencode/kv.json does not exist yet, opening the console (ctrl+p → toggle console) logs an error:

[ERROR] 'Failed to read KV state' {
  error: Error {
    code: 'ENOENT',
    path: '/home/<user>/.local/state/opencode/kv.json',
    syscall: 'open',
    errno: -2
  }
}

A missing kv.json is expected on first run — KV should start from empty state instead of logging an error. The file gets created lazily on first write.
