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).

Feature: Plugin Loader Coverage Boost
Scenarios targeting uncovered lines in the PluginLoader class:
- Lines 203-209: entry point load failure exception handler
- Lines 242, 244-246: validate_protocol fallback to issubclass when instantiation fails
- Lines 247-248: validate_protocol issubclass raises TypeError
Background:
Given the plugin loader module is imported
# -----------------------------------------------------------------------
# Entry-point discovery: failure path (lines 203-209)
# -----------------------------------------------------------------------
Scenario: Entry point that fails to load is skipped with a warning
Given the entry points are mocked with one that raises on load
When I call load_from_entry_points
Then the plugin result should be an empty descriptor list
And the failed entry point should have been logged as a warning
# -----------------------------------------------------------------------
# validate_protocol: instantiation fails, issubclass succeeds (lines 242, 244-246)
# -----------------------------------------------------------------------
Scenario: validate_protocol falls back to issubclass when instantiation fails
Given I have a class that requires constructor arguments
And I have a runtime checkable protocol the class satisfies via issubclass
When I call validate_protocol with the non-instantiable class and protocol
Then validate_protocol should return True
# -----------------------------------------------------------------------
# validate_protocol: instantiation fails, issubclass raises TypeError (lines 247-248)
# -----------------------------------------------------------------------
Scenario: validate_protocol raises ProtocolMismatchError when issubclass raises TypeError
Given I have a class that cannot be instantiated without arguments
And I have a protocol-like object that causes issubclass to raise TypeError
When I call validate_protocol expecting a mismatch error
Then a plugin-loader ProtocolMismatchError should be raised
# -----------------------------------------------------------------------
# validate_protocol: instantiation fails, issubclass returns False
# -----------------------------------------------------------------------
Scenario: validate_protocol raises ProtocolMismatchError when issubclass returns False
Given I have a class that cannot be instantiated without arguments
And I have a runtime checkable protocol the class does not satisfy
When I call validate_protocol expecting a mismatch error
Then a plugin-loader ProtocolMismatchError should be raised
