nested depth 2

// ============================================================================
// VERIFIED REGRESSION TEST - DO NOT MODIFY WITHOUT DISCUSSION
// ============================================================================
// Test: Nested Continuation Depth 2 (baseline)
// Feature: Flow with 2 levels of nested continuations
// Verifies: Basic nested continuation structure works
// Depth: start |> level1 |> level2 → result
// ============================================================================

// Chain: 10 → add-one → add-two → print result
// Depth 2: Two nested continuations
