httpreqid is a net/http compatible middleware designed for generating a request ID for each request if it doesn't already have one, and propagates it into the request context and response.
By default, this middleware will look for headers such as X-Request-ID, X-Correlation-ID, X-Trace-ID, Request-ID, Correlation-ID, and Trace-ID.
Additionally, this middleware provides a handler for log/slog that automatically adds the request ID to the log record.
