## What changed? - Introduce typeID for registered CHASM components and tasks - In longer term the relationship between component/task name and ID should be persisted (similar to namespace) ## Why? - Store less data - Decouple user visible name from internal implementation, making it possible in the future to rename components/tasks - Required for separate ID space work, where archetype information needs to be stored in all history tasks as well. ## How did you test it? - [x] built - [ ] run locally and tested manually - [x] covered by existing tests - [ ] added new unit test(s) - [ ] added new functional test(s)
