1. JobType Enum - All job type variants:
   - Ironic: IRONIC_STANDALONE, IRONIC_INTEGRATED, IRONIC_INSPECTOR
   - DevStack: DEVSTACK_MINIMAL, DEVSTACK_FULL
   - Service-focused: NEUTRON_FOCUSED, CINDER_FOCUSED, NOVA_FOCUSED
2. JobClassifier - Multi-heuristic classification:
   - _classify_by_parent() - Check parent job
   - _classify_by_services() - Strongest signal - check enabled services
   - _classify_by_projects() - Check required-projects
   - _classify_by_name() - Weakest signal - job name patterns
3. Key Methods:
   - classify_job() - Determine job type
   - get_required_services() - Map to container names
   - can_run_job() - Check if StackBox can run it
   - analyze_job() - Complete analysis for GitOps → returns all info needed for manifest
