Analyze the following user command and extract the intent, entity, and parameters.

User Command: "{userInput}"

Available intents:
- CREATE: User wants to create a new entity
- READ: User wants to read/query entities
- UPDATE: User wants to update an existing entity
- DELETE: User wants to delete an entity
- QUERY: User wants to execute a database query (SQL statements)

Available entities and their fields:

**Projekt** (Real estate project):
- id: string (primary key)
- mandateId: string (mandate ID)
- label: string (project designation/name)
- statusProzess: string enum (Eingang, Analyse, Studie, Planung, Baurechtsverfahren, Umsetzung, Archiv)
- perimeter: GeoPolylinie (geographic boundary, JSONB)
- baulinie: GeoPolylinie (building line, JSONB)
- parzellen: List[Parzelle] (plots belonging to project, JSONB)
- dokumente: List[Dokument] (documents, JSONB)
- kontextInformationen: List[Kontext] (context info, JSONB)

**Parzelle** (Plot/parcel):
- id: string (primary key)
- mandateId: string (mandate ID)
- label: string (plot designation)
- strasseNr: string (street and house number)
- plz: string (postal code)
- kontextGemeinde: string (municipality ID, Foreign Key to Gemeinde table)
- bauzone: string (building zone, e.g. W3, WG2)
- az: float (Ausnützungsziffer)
- bz: float (Bebauungsziffer)
- vollgeschossZahl: int (number of allowed full floors)
- gebaeudehoeheMax: float (maximum building height in meters)
- laermschutzzone: string (noise protection zone)
- hochwasserschutzzone: string (flood protection zone)
- grundwasserschutzzone: string (groundwater protection zone)
- parzelleBebaut: JaNein enum (is plot built)
- parzelleErschlossen: JaNein enum (is plot developed)
- parzelleHanglage: JaNein enum (is plot on slope)

**Important relationships:**
- Projekte contain Parzellen (projects have plots)
- Parzelle links to Gemeinde (via kontextGemeinde)
- Gemeinde links to Kanton (via id_kanton)
- Kanton links to Land (via id_land)
- Location queries (city, postal code) should use Parzelle.kontextGemeinde (municipality name will be resolved to ID)
- Projekt does NOT have location fields directly - location is stored in associated Parzellen

Return a JSON object with the following structure:
{{
    "intent": "CREATE|READ|UPDATE|DELETE|QUERY",
    "entity": "Projekt|Parzelle|Dokument|Kanton|Gemeinde|null",
    "parameters": {{
        // Extracted parameters from user input
        // For CREATE/UPDATE: include all relevant fields using EXACT field names from above
        // For READ: include filter criteria using EXACT field names (id, label, plz, kontextGemeinde, etc.)
        // For DELETE: include entity ID if mentioned
        // For QUERY: include queryText if SQL is detected
        // IMPORTANT: Use only field names that exist in the entity definition above
    }},
    "confidence": 0.0-1.0  // Confidence score for the analysis
}}

Examples:
- Input: "Erstelle ein neues Projekt namens 'Hauptstrasse 42'"
  Output: {{"intent": "CREATE", "entity": "Projekt", "parameters": {{"label": "Hauptstrasse 42"}}, "confidence": 0.95}}

- Input: "Zeige mir alle Projekte"
  Output: {{"intent": "READ", "entity": "Projekt", "parameters": {{}}, "confidence": 0.9}}

- Input: "Zeige mir Projekte in Zürich"
  Output: {{"intent": "READ", "entity": "Parzelle", "parameters": {{"kontextGemeinde": "Zürich"}}, "confidence": 0.9}}
  Note: Location queries should query Parzelle, not Projekt directly

- Input: "Zeige mir Parzellen mit PLZ 8000"
  Output: {{"intent": "READ", "entity": "Parzelle", "parameters": {{"plz": "8000"}}, "confidence": 0.95}}

- Input: "Aktualisiere Projekt XYZ mit Status 'Planung'"
  Output: {{"intent": "UPDATE", "entity": "Projekt", "parameters": {{"id": "XYZ", "statusProzess": "Planung"}}, "confidence": 0.85}}

- Input: "SELECT * FROM Projekt WHERE label = 'Test'"
