TDD expected-fail tests proving bug #822 exists:
CheckpointService.rollback_to_checkpoint() returns a successful
RollbackResult but does not execute git reset --hard. Files modified
after the checkpoint remain unchanged after rollback.
Also fixes Robot Framework timeout robustness across the entire test
suite: all Run Process calls now use on_timeout=kill (prevents
SIGTERM-induced -15 exit codes under CI load) and timeouts increased
to 120s (prevents premature kills during heavy parallel execution).

Renamed src/cleveragents/acp/ to src/cleveragents/a2a/ and all 13
Acp* classes to A2a* per ADR-047 (A2A Standard Adoption). Updated
all imports, structlog event names (acp.* → a2a.*), field names
(acp_version → a2a_version), and test references across the entire
codebase. This is a cosmetic rename only — no behavioral changes.

Add AsyncResourceTracker (core/async_cleanup.py) providing a central
registry for async resources with timeout-bounded close_all(), async
context manager support, and a __del__ finalizer that logs leaked
resources by name.
Enhance LangGraphBridge with cleanup_tasks_async() that awaits
in-flight tasks with a deadline instead of fire-and-forget cancel().
Add cancellation_reasons dict to trace why tasks were cancelled.
Add StateManager.close() to properly release checkpoint file handles
and complete the RxPY BehaviorSubject. Add AcpEventQueue.close() to
dispose all subscriptions.
Includes 14 Behave scenarios (67 steps), Robot integration tests,
ASV benchmarks, and docs/reference/async_safety.md.
ISSUES CLOSED: #321
