Idiomatic Go client wrapping the FastAPI surface in server.py — Healthz,
Run, UploadFile/UploadReader, and admin token CRUD. stdlib net/http only,
context-first signatures, typed errors (ErrAuth sentinel, RunFailure for
/run 502s, APIError for other 4xx/5xx, TransportError for network/EOF).
RunResult.Result is captured as json.RawMessage and materialized via
.AsJSON(out) / .AsText() because claude returns either parsed JSON or
plain text depending on prompt. UploadFile streams via io.Pipe + multipart
without buffering the file in memory.
