When a `var` is not explicitly given an initializer, initialize it in one of two ways: * If its type implements the new interface `Core.Default`, call `Core.Default.Op` to initialize it. * Otherwise, if its type implements `UnformedInit`, leave it in an unformed state. For now, this is always an uninitialized state, but that will change in the future. * If neither of those apply, the `var` declaration is ill-formed. This is a step towards implementing leads decision #6739 and proposals #257 and #5913. Assisted-by: Gemini 3.1 Pro via Antigravity --------- Co-authored-by: Geoff Romer <gromer@google.com>
