- Remove try! force operation that could crash on in-memory container failure
- Implement cascading fallback strategy with 3 initialization attempts:
1. Persistent storage (normal operation)
2. In-memory storage with user warning
3. Ultra-minimal default container
- Add containerInitializationFailed flag to track critical failures
- Extract container creation into static helper methods for better error handling
- Show user-friendly error dialog and graceful termination on total failure
- Only use preconditionFailure as absolute last resort after all attempts fail
Addresses AI code reviewer feedback about unsafe force operations.
