Baseline: Ausgangszustand vor Modularisierung
Erster Commit des bestehenden monolithischen WinForms-Copytraders, inklusive der Alt-Backups (*.bak), damit diese dauerhaft in der Historie rekonstruierbar bleiben. Threema-Lib unter libs/ wurde vendored (nested .git entfernt). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
