Research direction

Start with the discussion in WebAssembly/binaryen pull request 5143, then trace how Asyncify currently handles exception-related control flow. Define the required try-catch behavior and the WebAssembly MVP lowering approach before identifying implementation and test locations; done means Asyncify supports the requested try-catch cases with coverage for the lowered output.
