feat: Phase 4 - Join Nodes and Path Consolidation
Backend Implementation (v0.9m, workflow 0.5.0):
- join_evaluator.py (394 lines): Join-Strategie-Evaluator
- evaluate_join_node(): Hauptlogik für Join-Node Execution
- Join-Strategien: wait_all, wait_any, best_effort
- Skip-Handling: ignore_skipped, use_placeholder, require_minimum
- Result Consolidation: merge analysis_cores, combine signals
- Partial Execution: korrekte Behandlung von SKIPPED/FAILED Pfaden
- workflow_executor.py: execute_join_node() Integration
- BFS-Traversierung erweitert für Join-Nodes
- NodeExecutionState List → Dict Konvertierung für Signale
- Signal-Name-Kollisionen via node_id Präfix gelöst
Testing (49 Tests passing):
- test_phase4_join_nodes.py: 18 neue Unit Tests
- Join-Strategien (wait_all, wait_any, best_effort)
- Skip-Handling (ignore, placeholder)
- Result Consolidation (merge, combine)
- Partial Execution (mixed status paths)
- Helper Functions (collect, check, merge, combine)
- Backward Compatibility: 31 Phase 2/3 Tests (alle passing)
- test_phase2_workflow_executor.py: 1 Test aktualisiert
- test_phase3_logic_evaluator.py: 20 Tests unverändert
