Fügt CLI-Toolverwaltung und erweiterte UI-Funktionen hinzu

Ermöglicht die Verwaltung (Erstellen, Auflisten, Ausführen) von Tools über eine Befehlszeilenschnittstelle für Automatisierung und Integration. Die Benutzeroberfläche wurde mit dedizierten Ansichten für Toolerstellung und -bearbeitung, In-App-Lua-Hilfe sowie kontextsensitiven Menüs erweitert. Neue Abhängigkeiten (CLI11, rang) wurden integriert und eine umfassende Testsuite hinzugefügt. Die Lizenzierung wurde auf AGPL-3.0 umgestellt und ein Kontributionsleitfaden bereitgestellt.

+`Toolbox.exe` provides a machine-readable JSON interface without starting the GUI:
+
+```text
+Toolbox.exe list
+Toolbox.exe create --name "My Tool" --description "Example" --script-file start.lua --timeout 30
+Toolbox.exe run "My Tool"
+Toolbox.exe -h
+```
+
+Use `--home <path>` before the command to target a different user directory. `-h` and `--help` show the human-readable, colored help. Colors are selected automatically and can be overridden with `--color always` or `--color never`. Operational commands continue to write exactly one JSON object to stdout and use a non-zero exit code on failure.
+
+Tools are trusted local Lua programs. `run` exposes the same `os`, `io`, and `package` libraries as the Toolbox GUI, so agents should only execute reviewed tools.

+- Gemeinsamen Factory-/Lifecycle-Helper fuer `saucer::window` und `saucer::smartview` einfuehren.
+- Pro Fenster einen expliziten WebView2-Storage-Pfad vergeben, damit weitere Fenster nicht in der Environment-Erzeugung haengen.
+- Embedded Resources, Navigation-Policy, Icon, Hintergrund, DevTools und Close-/Hide-Verhalten zentral konfigurieren.
+- `show()`, `focus()`, Positionierung und Wiederverwendung als einheitlichen Fenster-Workflow kapseln.
+- Einen kleinen nativen Smoke-Harness fuer das Erzeugen und Anzeigen eines zweiten Fensters bereitstellen.

+### 9. Agentenschnittstelle
+
+Status: erste CLI-Schnittstelle umgesetzt.
+
+- Eigenes `toolbox-cli`-Target, damit Agenten nicht vom GUI-/Saucer-Lifecycle abhaengen.
+- Maschinenlesbare JSON-Ausgabe und belastbare Exit-Codes fuer `list`, `create` und `run`.
+- `--home` erlaubt isolierte Agentenlaeufe und Tests ohne Zugriff auf das echte Benutzerverzeichnis.
+- Als naechsten Schritt gemeinsame synchrone Lua-Ausfuehrungslogik fuer GUI und CLI extrahieren, damit Timeout-, Library- und Fehler-Policy nicht auseinanderlaufen.
+- Optional spaeter MCP als duenner Adapter ueber dieselben Core-Operationen anbieten.
