http-type 21.13.2

A comprehensive Rust type library for HTTP operations and concurrent programming. Provides core HTTP types (Request/Response with builder patterns, Method, HttpStatus, HttpVersion, ContentType, FileExtension with MIME mapping, Cookie parsing/building, HttpUrl parsing, WebSocket frame/opcode, protocol upgrade types, stream/task management, panic handling), thread-safe concurrent wrappers (ArcMutex, ArcRwLock, BoxRwLock, RcRwLock), dynamic dispatch types (BoxAny, RcAny, ArcAny with Send/Sync variants), high-performance hash collections (HashMapXxHash3_64, HashSetXxHash3_64), and static lifetime utilities (BoxLeak, Lifetime trait).
