Subject: [PATCH] Add /qa-301 Netlify function for Prerender 3xx testing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A second QA-only endpoint alongside /qa-status. Always returns a real
HTTP 301 with Location: https://weirdanimals.life/, set by the function
itself. Used to test Prerender's handling of 3xx responses on a clean,
page-looking URL.

- netlify/functions/qa-301.ts: new function returning 301 + Location.
- netlify.toml: add /qa-301 -> /.netlify/functions/qa-301 rewrite. The
  status = 200 here is the rewrite TYPE (proxy), not a forced response
  code — Netlify preserves the function's 301 status AND its Location
  header through the rewrite. Placed between the existing /qa-status
  rewrite and the SPA /* catch-all so it is not swallowed. The existing
  /qa-status rewrite and function are untouched.

No app routes, pages, or dependencies changed.
