Claude Bot 15ebc6a182 fix(spawn): protect ReadableStream from GC when used as stdin via Response ...

When `stdin: new Response(data)` is passed to `Bun.spawn`, the Response
body is converted to a ReadableStream and stored in the Stdio union.
Previously, this stored a bare ReadableStream (containing only a raw
JSValue), which was not protected from garbage collection. Between
extraction and when FileSink.assignToStream() creates a Strong reference,
process spawning and option processing could trigger GC cycles that
collect the unprotected ReadableStream, causing heap corruption.

Fix by changing Stdio.readable_stream from ReadableStream to
ReadableStream.Strong, which holds a C++ JSC Strong reference that
prevents the GC from collecting the stream value.

Closes #26979
