fix(test): align TDD bug #647 assertions with expected-fail inversion flow

Browse Source 
Updated Behave and Robot TDD tests for issue #648 to assert correct behavior while tagged with tdd_expected_fail, so listener/hook inversion works as intended. Also hardened test isolation and reliability by adding in-memory engine cache cleanup, per-run plan IDs, stricter assertion semantics, reduced Robot timeout, and an issue-resolution markdown response for Coree review comments.
