## 2.16.0

**`(feat):`** Add support for per-endpoint auth routing. When the API-level auth requirement is
`ENDPOINT_SECURITY`, each endpoint now applies only the auth scheme(s) it declares in
its IR `security` field (OR across the list of requirements, AND within a requirement,
and no auth when `security` is empty), instead of applying every configured credential
to every request. Behavior for the `ALL` and `ANY` auth requirements (the common cases)
is unchanged.
