fix(tests): resolve CI gate failures in restored e2e test suite

Six targeted fixes to make unit_tests and e2e_tests quality gates pass:

1. tdd_a2a_sdk_dependency.feature: update scenario to check Client class
   instead of A2AClient — newer a2a-sdk removed the legacy alias.

2. cli_main_cov3_steps.py: reformat `except (BaseException)` multiline
   to `except BaseException` single-line to pass ruff format check.

3. wf05_db_migration.robot: unwrap CLI JSON envelope before counting
   decision nodes — plan tree --format json wraps nodes in
   {"exit_code":0,"data":[...]} so the lambda was finding 0 nodes.

4. m2_acceptance.robot: restore tdd_issue tdd_issue_4189 tdd_expected_fail
   — actor compiler bug #4189 still causes rc=1; removing the tag made
   CI report it as a hard failure instead of an expected one.

5. wf12_hierarchical.robot: restore tdd_issue tdd_issue_4188
   tdd_expected_fail — 4-project LLM test gets SIGKILL (OOM) in CI;
   restoring the tag makes the expected failure invert to PASS.

6. m5_acceptance.robot: restore permanent tdd_issue tdd_issue_4188/4189
   reference tags on all 21 test cases (only tdd_expected_fail was
   legitimately removed by the JSON envelope fix; the permanent
   regression-guard tags must never be removed per CONTRIBUTING.md).
