feat(ui): Cheat-Sheet-Fenster im Hilfe-Menue

Sechs Markdown-Sheets (git, Conventional Commits, Claude CLI, Claude-Config, dotnet CLI, PowerShell) als EmbeddedResource, gerendert im modelosen, per Topmost anpinnbaren CheatSheetsWindow. MarkdownView bekommt dafuer das Opt-in CommandRows: `befehl` - beschreibung wird zu Mono-Chip + Copy-Button, jede ##-Sektion landet in einem Expander. Enthaelt ausserdem: Mission Control wird beim Oeffnen aus dem Minimiert-Zustand geholt, nicht nur aktiviert.
