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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
