fun: upgrade TS client interceptors to fun-client parity (v1.2.0)

- request interceptor now receives the mutable per-request state map (token injection)
- response interceptor may return a replacement result (central token swap / error handling)
- fetch failures normalized to result status=4 (network error) instead of throwing
- stream requests also pass through request interceptors with state copy
