safe_mode emits `if (should_enter_safe_mode(...)) return` via cg.add(RawExpression(...)) to short-circuit the rest of setup() and boot into safe mode. With setup() split into per-component IIFEs, that `return` was only exiting the lambda, so the rest of setup() ran anyway — breaking safe-mode recovery. Add IIFEUnsafeStatement, a Statement wrapper that marks its containing component's block for flat emission (no IIFE). safe_mode wraps its return expression in it. cpp_main_section detects any such statement in a group and emits that group flat so control-flow constructs like `return` still affect setup() itself. IIFEUnsafeStatement.__str__ routes its inner through statement() so bare Expression subclasses pick up the terminating semicolon. Reported by @swoboda1337.
