• 43ca80a: Make redirect handling configurable in all five languages

  Redirects were followed unconditionally everywhere, and TypeScript went further:
  merge({}, init, { redirect: 'follow' }) put the literal last, so a caller
  passing redirect: 'manual' had it silently overwritten. Python hardcoded
  follow_redirects=True into the httpx kwargs; Rust, Go and .NET set nothing and
  inherited platform defaults that follow up to 10 hops.

  That is a security gap, not just an ergonomic one. A caller who resolves a
  hostname and checks it against an SSRF allowlist has that guard defeated by a 302
  to an internal address, because the check was performed on the original host. And
  RFC 8461 forbids following redirects when fetching an MTA-STS policy.

  • TypeScript — redirect is honoured (defaults first, caller last)
  • Python — FetchOptions.follow_redirects
  • Rust — RequestInit.follow_redirects: Option<bool> (None inherits, so a
    client-level default survives a per-request ..Default::default())
  • Go — ClientBuilder.WithFollowRedirects, applied to a caller-supplied
    *http.Client too
  • .NET — SmooFetchOptions.FollowRedirects / WithFollowRedirects

  Honouring the option was not sufficient on its own: in TS, Rust, Go and .NET a
  3xx is neither "ok" nor "redirected", so it was raised as an error and the option
  was undone a line later. Each now returns a deliberately-unfollowed 3xx as an
  ordinary response. Defaults are unchanged — everything still follows unless a
  caller says otherwise.
