## Create Classify Job

**post** `/api/v2/classify`

Create a classify job.

Classifies a document against a set of rules. Set `file_input`
to a file ID (`dfl-...`) or parse job ID (`pjb-...`), and provide
either inline `configuration` with rules or a `configuration_id`
referencing a saved preset.

Each rule has a `type` (the label to assign) and a `description`
(natural language criteria). The classifier returns the best
matching rule with a confidence score.

The job runs asynchronously. Poll `GET /classify/{job_id}` to
check status and retrieve results.

### Query Parameters
