Subject: [PATCH] =?UTF-8?q?fix:=20Workflow=20execute=20-=20prompt=5Fid=20?=
 =?UTF-8?q?=E2=86=92=20prompt=5Fslug?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Problem:**
Execute-Button funktionierte, aber Ausführung scheiterte mit
"Prompt not found: none" im Analysis Node.

**Root Cause:**
Mismatch zwischen Frontend (speicherte prompt_id/UUID) und
Backend (erwartete prompt_slug/String).

Backend WorkflowNode Model (workflow_models.py:193):
  prompt_slug: Optional[str] = Field(...)

**Änderungen:**
- WorkflowEditorPage.jsx: Dropdown auf slug umgestellt
  - value: prompt_slug statt prompt_id
  - onChange: selectedPrompt.slug statt .id
  - handleNodeUpdate: prompt_slug speichern

- workflowSerializer.js: Serialization/Deserialization
  - Serialize: prompt_slug statt prompt_id
  - Deserialize: node.prompt_slug lesen

**Testing:**
- Workflow mit Analysis Node neu erstellen
- Execute-Button sollte jetzt funktionieren

Part 2 Bugfix - Workflow Execution
