We had to change the build process of Lambdas to support deploying a mock version of the function. And we need to add a new command that deployed the debug stack.

Your existing CDK app should work with SST. The main difference is that SST deploys per stage (or environment). This allows you to do `sst start` that goes to one environment and `sst deploy --stage prod` that goes to another.
