 ### Changed
 - Minimum supported Zig version is now 0.16.0. Transports (HTTP, WebSocket, SSE), retry backoff, and receipt polling were migrated to the new `std.Io` interface; the library constructs a default blocking `std.Io` internally, so public signatures are unchanged. This is a breaking change for Zig 0.15 users
