fix: add required @a2a, @session, @cli tags to BDD feature files

Add domain-scenario Gherkin tags to all A2A, session, and CLI feature
files (30 files) so tests can be filtered individually via behave.

- 8 A2A feature files: @a2a tag
- 7 session feature files: @session tag
- 15 CLI feature files: @cli tag

ISSUES CLOSED: #9124

+- **BDD Feature File Tag Coverage** (#9124): Added required `@a2a`, `@session`, and `@cli` Gherkin tags to all A2A, session, and CLI feature files (30 files) to enable tag-based test filtering via `behave --tags=a2a,session,cli`. This restores the ability to selectively run test categories and enables CI to execute targeted test suites without running the full suite.

 - **Cross-actor subgraph cycle detection reads actor_ref field** (#1431): Fixed
   `_detect_subgraph_cycles()`, `_map_node()`, and the `compile_actor()` main loop
   in `src/cleveragents/actor/compiler.py` to read `actor_ref` from the top-level

CONTRIBUTORS.md

@@ -65,3 +65,4 @@ Below are some of the specific details of various contributions.
 * HAL 9000 has contributed the Definition-of-Done gating feature for the Apply phase (PR #8299 / issue #7927): `PlanLifecycleService.apply_plan` now evaluates DoD criteria before transitioning to Apply, raising `DoDGatingError` when required criteria fail and storing evaluation results in `plan.validation_summary`.
 * HAL 9000 has contributed the engine cache TOCTOU race condition fix (PR #8265 / issue #7566): added `MEMORY_ENGINES_LOCK` to `engine_cache.py` and wrapped the check-and-set operation in `UnitOfWork.engine` with `with MEMORY_ENGINES_LOCK:` to prevent concurrent threads from creating duplicate in-memory SQLite engine instances; also fixed a cache-hit bug where `self._engine` was never assigned on a cache hit.
 * HAL 9000 has contributed the plan correct JSON output envelope fix (PR #8662 / issue #8584): restructured `agents plan correct --format json` output to nest correction fields under `data.correction` and pass `command="plan correct"` to `format_output`, producing the spec-required CLI envelope. Added three BDD scenarios validating `data.correction.mode` (revert and append modes) and the `command` field.
+* HAL 9000 has contributed BDD feature file tag coverage improvements (#9124 / pr #9183): added required `@a2a`, `@session`, and `@cli` Gherkin tags to 30 feature files (8 A2A, 7 session, 15 CLI) to enable selective tag-based test filtering via `behave --tags=a2a,session,cli`.
