When ContextEval detects an InterruptError, wrap both the original error and the context cause using fmt.Errorf("%w: %w", ...) so that:

  • errors.Is(err, context.Canceled) works (new behavior)
  • errors.Is(err, context.DeadlineExceeded) works (new behavior)
  • errors.Is(err, InterruptError{}) works (preserved)
  • strings.Contains(err.Error(), "operation interrupted") works (backward compat)

Previously, the error was replaced entirely with context.Cause(ctx), which dropped the "operation interrupted" message that downstream consumers (e.g. Kubernetes) rely on for string matching.

Fixes #1195 while maintaining backward compatibility.
