Session file is corrupted - Invalid literal value

I'm using the .NET SDK, a few times now, after updating the NuGet version, some (not all) previous sessions become corrupt. This is the error i get when resuming a session -
```
System.IO.IOException: Communication error with Copilot CLI: Request session.resume failed with message: Session file is corrupted (line 355: ephemeral: Invalid literal value, expected true)
---> StreamJsonRpc.RemoteInvocationException: Request session.resume failed with message: Session file is corrupted (line 355: ephemeral: Invalid literal value, expected true)

```

Comece pela chamada reportada de SessionFeature.LoadSession na linha 215 de SessionFeature.Lifecycle.cs e rastreie o caminho ResumeSessionAsync do SDK. Inspecione os dados de sessão corrompidos ao redor da linha 355, especialmente o campo ephemeral, e determine uma falha reproduzível ou uma correção clara para lidar com arquivos de sessão inválidos.
