Subject: [PATCH] v0.2.1: wrap clean-lift headers in namespace oatpp_authkit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The four clean-lift headers (SecurityHeadersInterceptor,
BodySizeLimitInterceptor, JsonErrorHandler, RateLimiter) were copied
verbatim in v0.1.0 and left in the global namespace — consumers that
adopt the library alongside existing same-named classes (e.g. fewo-webapp
during the #417 swap) would hit ODR clashes.

Wrap them in the same namespace the v0.2 auth seams use. Patch bump; no
API surface change beyond the qualifier.
