actix-web 4.13.0: HTTP/2 Upload Throughput, MSRV Bump to Rust 1.88

release MEDIUM
actix-web 4.13.0 is the current tracked version. Key features worth noting for ODS: (1) HTTP/2 upload throughput improved via larger flow control window sizes with new HttpServer::h2_initial_window_size and h2_initial_connection_window_size tuning methods; (2) Added experimental-introspection feature to enumerate configured routes; (3) Fixed NormalizePath panic with scoped dynamic paths; (4) MSRV is now Rust 1.88 — ODS Rust toolchain at 1.94.1 satisfies this; (5) Ignores unparsable cookies rather than erroring.

ODS Impact

All ODS Rust backend services using actix-web (oid, docstore, pdf-engine, notification-hub, etc.). HTTP/2 window tuning is relevant for PDF upload in pdf-engine. Route introspection feature could assist ODS Dashboard API discovery.
