Coverage expansion tests for agent execution integration.
Tests cover critical code paths in:
- agent_execution_service.py: Agent execution lifecycle, state management
- execution_state_manager.py: State tracking, transitions
- Governance integration: Permission checks, maturity validation
- Error handling: Failures, retries, timeouts
Target: Cover critical integration paths (happy path + error paths) to increase coverage.
