feat: Handle literal comparisons that use = and comprehensions without loops

- emit AssertCondition for equality-only assignment plans (outside soft-assert mode) so rules like `0 = 1` fail under the VM just like the interpreter
- let comprehension bodies consume assertion failures by advancing or exiting their iteration context, both in run-to-completion and suspendable execution
