dtrentin 4cd7715594 fix(robustness): null guard WMI reads, dispose SHA256, abort LSV2 timeout (ISS-001, ISS-005, ISS-006) 
ISS-001: MachineFingerprint.GetFingerprint() — null-safe WMI property reads
  - processorID and SerialNumber accessed with ?. and ?? string.Empty
  - prevents NullReferenceException on machines with missing WMI properties

ISS-005: LicenseValidator.Validate() — SHA256CryptoServiceProvider in using block
  - disposed on all code paths (success and failure)

ISS-006: Lsv2Client.Connect() — close TcpClient on timeout
  - _tcp.Close() called when ConnectAsync.Wait() times out
  - aborts pending socket task instead of leaking thread-pool slot
