Struct WasmSend 

pub struct WasmSend<T>(/* private fields */);

Wrapper that unconditionally implements Send on WASM.

On native, WasmSend<T> is Send only if T: Send (no magic). On WASM, WasmSend<T> is always Send, allowing !Send types (like Writer wrapping a JsValue-backed response stream) to be moved into a Web Worker.

Safety contract

The caller must ensure that:

• The wrapped value is not actively used across threads simultaneously.
• When transferring to a Web Worker, any !Send JS-backed values inside must be None/uninitialized at transfer time and only populated inside the target worker (where JS objects belong to the local context).

FileDownloader satisfies this: writer is None when moved to the Worker, and ensure_writer() creates the HTTP stream inside the Worker.
