test(coverage): add Behave BDD tests to improve coverage across 52 source files
Added 52 new .feature files and corresponding _steps.py files targeting
previously uncovered code paths in the following areas:

- TUI layer: app, commands, persona (state/schema/registry), widgets,
  input (shell_exec, reference_parser)
- Application services: plan lifecycle/service/executor, session,
  project, repo indexing, correction, checkpoint, actor, llm_actors,
  strategy coordinator, resource file watcher, service retry wiring
- CLI commands: session, resource, repl, plan, db, automation_profile
- Domain models: retry_policy, resource_type, cost_budget,
  docker_compose_analyzer, detail_level, _sql_string_aware,
  _postgresql_helpers
- Core: circuit_breaker, retry_service_patterns
- Infrastructure: repositories, transaction_sandbox, strategy_registry,
  plugins/loader, container
- Config: settings
- Agents: plan_generation, context_analysis, auto_debug
- A2A: facade

All new tests follow the Behave/Gherkin BDD standard. Resolved step
definition collisions with unique prefixes. Fixed Alembic fileConfig
logger disabling issue (disable_existing_loggers=False).

ISSUES CLOSED: #1068

Feature: Circuit Breaker Coverage
Scenarios that exercise previously uncovered code paths in
the circuit_breaker module, focusing on edge-case exception
handling, stale-generation guards, and async equivalents.
Background:
Given the circuit breaker coverage module is imported
# --- Sync path: inner CircuitBreakerOpen during HALF_OPEN (lines 160-169) ---
Scenario: Sync call restores half-open permit when inner service raises CircuitBreakerOpen
Given a coverage circuit breaker with failure threshold 2 and fast recovery
And the coverage circuit breaker is transitioned to half-open state
When I sync-call a function that raises inner CircuitBreakerOpen
Then the caught exception should be a CircuitBreakerOpen
And the coverage half-open permit count should be restored
# --- Sync path: BaseException during HALF_OPEN (lines 191-195) ---
Scenario: Sync call restores half-open permit when function raises a BaseException subclass
Given a coverage circuit breaker with failure threshold 2 and fast recovery
And the coverage circuit breaker is transitioned to half-open state
When I sync-call a function that raises a KeyboardInterrupt
Then the caught exception should be a KeyboardInterrupt
And the coverage half-open permit count should be restored
# --- Async path: inner CircuitBreakerOpen during HALF_OPEN (lines 286-295) ---
Scenario: Async call restores half-open permit when inner service raises CircuitBreakerOpen
Given a coverage circuit breaker with failure threshold 2 and fast recovery
And the coverage circuit breaker is transitioned to half-open state
When I async-call a function that raises inner CircuitBreakerOpen
Then the caught exception should be a CircuitBreakerOpen
And the coverage half-open permit count should be restored
# --- Async path: BaseException during HALF_OPEN (covers async BaseException handler) ---
Scenario: Async call restores half-open permit when function raises a BaseException subclass
Given a coverage circuit breaker with failure threshold 2 and fast recovery
And the coverage circuit breaker is transitioned to half-open state
When I async-call a function that raises a KeyboardInterrupt
Then the caught exception should be a KeyboardInterrupt
And the coverage half-open permit count should be restored
# --- Stale generation discarded in _on_success (line 360) ---
Scenario: Stale half-open generation is discarded on success
Given a coverage circuit breaker in half-open state with generation 3
When _on_success is called with stale generation 1
Then the _on_success result should be False
And the coverage circuit breaker should still be half-open
# --- _on_failure when already OPEN (line 384) ---
Scenario: _on_failure is a no-op when circuit is already open
Given a coverage circuit breaker that is already in the open state
When _on_failure is called on the already-open breaker
Then the _on_failure result should be False
And the coverage circuit breaker state should still be open
And the failure count should not have changed
