Fern

Fern Definition and CLI

Capability area covering Fern's open-source (Apache-2.0) command-line interface and the proprietary Fern Definition API-description format. Core commands include `fern init`, `fern check`, `fern generate`, `fern login`, `fern token`, `fern export`, and `fern docs dev`. Endpoints are modeled from the CLI surface, not a hosted REST API.
