T1.8: Action Execution Failure Handling

Tests that failed action executions are handled gracefully.

Test Flow:
1. Create action that always exits with error (exit code 1)
2. Create rule to trigger action
3. Execute action
4. Verify execution status becomes 'failed'
5. Verify error message captured
6. Verify exit code recorded
7. Verify execution doesn't retry (no retry policy)

Success Criteria:
- Execution status: 'requested' → 'scheduled' → 'running' → 'failed'
- Exit code captured: exit_code = 1
- stderr captured in execution result
- Execution result includes error details
- Worker marks execution as failed
- Executor updates enforcement status
- System remains stable (no crashes)
