8.1.0

Added

• Invoke-WithExitCodeRetry - exit-code counterpart to Invoke-WithRetry
  for native commands (netsh, git, docker, wsl, ...) that signal
  failure through $LASTEXITCODE instead of a thrown exception. Reuses the
  existing backoff strategies; scope retries with an optional
  -RetryableExitCode set, or throw and use Invoke-WithRetry for
  predicate-based classification.
