`POST /v1/detect`

Detect the dominant language, script and base direction of a string, with a segment per language (no model). Built for short, code-switched input such as chat messages, search queries and voice transcripts: a brand, product name or acronym inside a Hebrew or Russian sentence ("PayPal", "iPhone", "API") does not change the dominant language, and Hebrew prefixes joined by a hyphen ("ה-API") are split correctly. Links and email addresses are ignored. Latin script is tagged `en`.
