test(res): add test for HEAD request redirect

v1rtl · claude · v1rtl · commit 80a8c70e37bb · 2026-02-01T11:20:07.000+02:00
Add test covering the HEAD method branch in redirect.ts which
sends an empty body for HEAD requests.

Improves redirect.ts coverage:
- Statements: 94% -&gt; 100%
- Branches: 75% -&gt; 100%
