Get feature by type and ID

### Returns

- `geo_json_feature: object { geometry, properties, type, id }`

  GeoJSON Feature representing an OSM element. Tags from the original OSM element are flattened directly into `properties` (not nested under a `tags` key). Metadata fields `@type` and `@id` identify the OSM element type and ID within properties.

  - `geometry: object { coordinates, type }`

    GeoJSON Geometry object per RFC 7946. Coordinates use [longitude, latitude] order. 3D coordinates [lng, lat, elevation] are used for elevation endpoints.

    - `coordinates: array of number or array of array of number or array of array of array of number or array of array of array of array of number`

      Coordinates array. Nesting depth varies by geometry type: Point = [lng, lat], LineString = [[lng, lat], ...], Polygon = [[[lng, lat], ...], ...], etc.

      - `Point: array of number`

        [longitude, latitude] or [longitude, latitude, elevation]

      - `LineString or MultiPoint: array of array of number`

        Array of [lng, lat] positions

      - `Polygon or MultiLineString: array of array of array of number`

        Array of linear rings / line strings

      - `MultiPolygon: array of array of array of array of number`

        Array of polygons

    - `type: "Point" or "LineString" or "Polygon" or 3 more`

      Geometry type

      - `"Point"`

      - `"LineString"`

      - `"Polygon"`

      - `"MultiPoint"`

      - `"MultiLineString"`

      - `"MultiPolygon"`

  - `properties: map[unknown]`

    OSM tags flattened as key-value pairs, plus `@type` (node/way/relation) and `@id` (OSM ID) metadata fields. May include `distance_m` for proximity queries.

  - `type: "Feature"`

    Always `Feature`

    - `"Feature"`

  - `id: optional string`

    Compound identifier in `type/osm_id` format
