Fix test runner paths, all 203 tests pass

Spec tests (Python host): 43 CEK + 24 continuations + 90 types = 157
Web tests (Python host): 20 signals + 26 CEK reactive = 46
Total: 203 tests, 0 failures.

Fixed: continuation test bootstrapper path, type test spec dir path.
Both bootstrappers verified: Python (5993 lines), JS (387KB).
