R8: Accounting- + Supervisor-Modul + Core-Datenfundament (S-0)
Portierung der beiden fehlenden Grundbausteine aus PolytraderSharp (voller Ausbau). Core S-0 (Datenfundament fuer Analyse/Forensik): - core_decision_journal + core_order_events (+ ReasonCode/Decision/OrderEvent-Enums), IDecisionJournal/IOrderEventLog mit fehlertoleranten EF-Impls (Handel bricht nie). - SignalId-Durchreichung TradeSignal -> ExecutionService -> core_trade_history; ExecutionService schreibt an jeder Verzweigung Journal/Order-Events. - JSONL-Log-Sink (LogJson + Dual-Sink), pure Analytik: RealizedPnlEngine (FIFO), TradeAnalytics, DossierBuilder. Migration AddAnalysisFoundation. Accounting-Modul (acc_): unabhaengiger IBKR-Kontoauszug (Activity Flex Query) hinter Interfaces mit Offline-Null-Stubs -> append-only Ledger + Periodenabrechnung/BWA + FX (USD/EUR) + CSV/PDF (PDFsharp/MigraDoc). Steuerschicht bewusst offen (Platzhalter-Tab). Kein Handel. Migration InitialAccounting. Supervisor-Modul (sup_): read-only OpenRouter-Agent (Function-Calling-Loop) + read-only Tool-Registry (8 Tools) + Profile + Dossier-Browser + Counterfactual-Job (Stub) + Tagesbericht/MCP-Light (opt-in). Migration InitialSupervisor. Verdrahtung: Program.cs (beide Module + Icons), slnx/App/Tests-Referenzen, provision-db.ps1, AppSettings-Sektionen, docs/konzepte, README. Tests: 79 -> 117 gruen (FIFO/KPIs/Dossier/JSONL, Classifier/Engine/FX/Idempotenz, OpenRouter/Registry/Agent/MCP, STA-Konstruktion beider neuen Fenster).
