Add ConfigReloadHandle with Arc<ArcSwap<DynamicConfig>> for lock-free reads on the request hot path and tokio::sync::Mutex-serialized reload. Add static config change detection via diff_static_config(). Add DynamicConfig validation (rate_limit, body_limit, site checks). Add PartialEq derives to config types. Include unit tests for ArcSwap swap visibility, invalid config rejection, and concurrent reload serialization.
