build: separate typechecking and build tsconfigs

This change separates the TypeScript configuration into two configurations:

- `tsconfig.json`: Non-artifact-emitting configuration for development-
  time typechecking
- `tsconfig.build.json`: Artifact-emitting configuration used to build
  the project

This includes no functional changes and is simply setup for future
typechecking improvements.
