R1: Umbau auf Multi-Projekt-Struktur (Vorbild PolytraderSharp) Kurskorrektur: Vorbild ist PolytraderSharp (C#), nicht die veraltete Python-Version. Reiner Strukturumbau, Verhalten unveraendert. - src/IBKRTrader.Core (classlib): Core-Code + UI-Contract (ModuleFormBase, WindowManager) - src/IBKRTrader.Modules.CongressTrading (classlib, referenziert nur Core) - Root: IBKRTrader.App (WinExe) referenziert Core + Modul - tests/IBKRTrader.Tests: Referenzen auf Core + Modul - Neue .slnx; ungenutztes HtmlAgilityPack entfernt - docs/ARCHITECTURE.md: korrigierter Ziel-Stand + R-Phasenplan - Build + 38/38 Tests gruen; App startet Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> @
