zenhttp: add FollowRedirects option to HttpClient (#982)

- Adds `FollowRedirects` (default `false`) and `MaxRedirects` (default `5`) fields to `HttpClientSettings`.
- When `FollowRedirects` is enabled, the curl backend sets `CURLOPT_FOLLOWLOCATION` and `CURLOPT_MAXREDIRS` so HTTP 3xx redirects are handled transparently in the transport layer — callers no longer need to parse `Location` headers and re-issue requests themselves.
- Defaults are off, so existing callers see no behavior change.
