Function validateGeoJSON

validateGeoJSON(
geojson: Record<string, unknown> | null | undefined,
options?: ValidatorOptions,
): { valid: boolean; error: string | null }
Validates the structure of a GeoJSON object.

⚠️ Structural only: it checks that the type is known and that a FeatureCollection carries a features array. It does not walk the geometries, so coordinates are not range-checked — pair it with validateCoordinates where that matters.

Like its siblings it throws a ValidationError when throwOnError is set — but the throw is delegated to the shared _geoJSONCheck helper rather than raised here, so this block carries no @throws tag: TSD-03 requires the tag to sit above a literal throw, and it does not follow the call graph.
Parameters
- geojson: Record<string, unknown> | null | undefined
  Candidate GeoJSON object.
- options: ValidatorOptions = {}
  See ValidatorOptions.
Returns { valid: boolean; error: string | null }
{ valid, error }; error is null when valid.
Example
```
// FeatureCollection valide
const geojson = {
    type: "FeatureCollection",
    features: [
        {
            type: "Feature",
            geometry: { type: "Point", coordinates: [-73.5673, 45.5017] },
            properties: { name: "Montreal" },
        },
    ],
};
GeoLeaf.Validators.validateGeoJSON(geojson);
// Returns: { valid: true, error: null }

// GeoJSON invalide (features manquant)
GeoLeaf.Validators.validateGeoJSON({ type: "FeatureCollection" });
// Returns: { valid: false, error: 'FeatureCollection must have a features array' }
```
