Subject: [PATCH] fix(s28): api-reference handle ~/path ASP.NET convention
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ASP.NET Core convention для HttpX-атрибутов: `~/path` означает
'absolute from root, ignore class [Route]'. До фикса генератор клеил
`base-route` + `~/path` → невалидный `/~/connect/token`.

Теперь tilde корректно срезается, /connect/token виден в reference.

Также добавлен unit test ApiReferenceDocsJobTests (Sprint 28) для
lock-down regex behavior на double-nested generics.
