test(a2a): cover facade DI fallbacks and message/send validation
Add 5 BDD scenarios to features/a2a_facade_coverage_boost.feature that
exercise previously uncovered paths in src/cleveragents/a2a/facade.py:

- _handle_message_send raises ValueError on empty session_id (line 469)
- _handle_message_send raises ValueError on empty message (line 471)
- _build_actor_resolver_for_session_workflow exception fallback (411-425)
- _build_actor_options_resolver_for_session_workflow exception fallback
  (434-452)
- _provider_registry property read (line 160)

Pushes overall coverage past the 96.5% slipcover --fail-under threshold
that the CI / coverage gate enforces; the prior run was 96.4%.

Feature: A2A local facade coverage boost — uncovered validation paths
As a developer maintaining the A2A local facade
I want all error-handling and validation paths exercised
So that edge-case regressions are caught early
# ---------------------------------------------------------------
# Constructor validation (line 82)
# ---------------------------------------------------------------
Scenario: Constructing A2aLocalFacade with a non-dict raises TypeError
When I try to create an A2aLocalFacade with a non-dict services argument
Then a TypeError should be raised with message "services must be a dict or None"
# ---------------------------------------------------------------
# plan.execute — empty plan_id with service wired (line 256)
# ---------------------------------------------------------------
Scenario: plan.execute with empty plan_id and wired service returns error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "plan.execute" with params {"plan_id": ""}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "plan_id is required"
Scenario: plan.execute with missing plan_id param and wired service returns error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "plan.execute" with params {}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "plan_id is required"
# ---------------------------------------------------------------
# plan.status — empty plan_id with service wired (line 266)
# ---------------------------------------------------------------
Scenario: plan.status with empty plan_id and wired service returns error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "plan.status" with params {"plan_id": ""}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "plan_id is required"
Scenario: plan.status with missing plan_id param and wired service returns error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "plan.status" with params {}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "plan_id is required"
# ---------------------------------------------------------------
# plan.diff — empty plan_id with service wired (line 281)
# ---------------------------------------------------------------
Scenario: plan.diff with empty plan_id and wired service returns error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "plan.diff" with params {"plan_id": ""}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "plan_id is required"
Scenario: plan.diff with missing plan_id param and wired service returns error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "plan.diff" with params {}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "plan_id is required"
# ---------------------------------------------------------------
# plan.apply — empty plan_id with service wired (line 295)
# ---------------------------------------------------------------
Scenario: plan.apply with empty plan_id and wired service returns error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "plan.apply" with params {"plan_id": ""}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "plan_id is required"
Scenario: plan.apply with missing plan_id param and wired service returns error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "plan.apply" with params {}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "plan_id is required"
# ---------------------------------------------------------------
# message/send validation (lines 468-471)
# ---------------------------------------------------------------
Scenario: message/send with empty session_id returns validation error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "message/send" with params {"session_id": "", "message": "hi"}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "session_id is required"
Scenario: message/send with empty message returns validation error
Given a coverage-boost facade with a mock PlanLifecycleService
When I dispatch coverage-boost operation "message/send" with params {"session_id": "s1", "message": ""}
Then the coverage-boost response status should be "error"
And the coverage-boost response error code should be "INTERNAL_ERROR"
And the coverage-boost response error message should contain "message is required"

# Static DI-fallback resolvers (lines 411-425, 434-452)
# ---------------------------------------------------------------
Scenario: _build_actor_resolver_for_session_workflow falls back when DI container raises
When I call the static resolver builder with a failing DI container
Then the static resolver result should be None
Scenario: _build_actor_options_resolver_for_session_workflow falls back when DI container raises
When I call the static options-resolver builder with a failing DI container
Then the static options-resolver result should be None
# ---------------------------------------------------------------
# Service accessor: _provider_registry property (line 160)
# ---------------------------------------------------------------
Scenario: _provider_registry property reads from services dict
Given a coverage-boost facade wired with a mock ProviderRegistry
When I access the _provider_registry property
Then the provider registry accessor should return the mock
