Refactor Program and tests for improved resource management

- Implement IDisposable in Program.cs for better resource handling.
- Add CancellationTokenSource for managing long-running tasks.
- Update process handling with using statements and error logging.
- Enhance BlakeServeCommandTests with increased timeouts and exception assertions.
- Refactor RunProcessAsync in TestFixtureBase for clarity and improved cancellation handling.
- Update ProcessResult to include a nullable Canceled property.
