Module correlation 

Per-request correlation context.

CorrelationContext carries request-scoped state — correlation and request IDs, flow marker, user ID, raw body, headers, query parameters, decoded multipart payload, arbitrary key/value data, and pagination state — through handlers. It is cheaply clonable via Arc and can also be propagated via the CORRELATION_CTX task-local.

let ctx = CorrelationContext::new();
let page: Option<String> = ctx.query_param("page");
