Subject: [PATCH] fix: add catch-all S3 route for path-style requests
 (/{bucket}/{key})
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bun's '/' route only matches root path '/'. S3 SDK clients using
forcePathStyle:true send ALL requests to /{bucket}/{key} which never
matched any route → 404. Added '/*' catch-all that checks for S3
auth headers before dispatching.
