014 void chaining nested

// Test: Void event chaining with nested continuations
// When chaining void -> event with branches, should parse nested continuations correctly
// Pattern: ~void_event() |> branching_event()
//              | branch1 |> _
//              | branch2 |> _

// Chain void event to branching event, then handle branches with nested continuations
