Fixes: #64292

stream/iter's fromSync() rejected any input that exposed
Symbol.asyncIterator, even when the same input also exposed
Symbol.iterator.

This updates fromSync() to reject only inputs without a synchronous
iteration path, allowing dual sync/async iterables and thenable sync
iterables to be consumed through their synchronous iterator.

stream: prefer sync iterator in fromSync
fccb76b
When an input provides Symbol.iterator, fromSync() should consume the
synchronous iterator instead of rejecting the input because it also
exposes an asynchronous or promise-like protocol.
Continue rejecting async-only iterables and promise/thenable-only
inputs, but allow sync iterables that also define Symbol.asyncIterator
or then().

Fixes: #64292
stream/iter's fromSync() rejected any input that exposed
Symbol.asyncIterator, even when the same input also exposed
Symbol.iterator.
This updates fromSync() to reject only inputs without a synchronous

iteration path, allowing dual sync/async iterables and thenable sync

iterables to be consumed through their synchronous iterator.

Fixes: #64292
stream/iter's fromSync() rejected any input that exposed
Symbol.asyncIterator, even when the same input also exposed
Symbol.iterator.
This updates fromSync() to reject only inputs without a synchronous

iteration path, allowing dual sync/async iterables and thenable sync

iterables to be consumed through their synchronous iterator.

stream: prefer sync iterator in fromSync
ce6448e
When an input provides Symbol.iterator, fromSync() should consume the
synchronous iterator instead of rejecting the input because it also
exposes an asynchronous or promise-like protocol.
Continue rejecting async-only iterables and promise/thenable-only
inputs, but allow sync iterables that also define Symbol.asyncIterator
or then().

stream: prefer sync iterator in fromSync
ce6448e
When an input provides Symbol.iterator, fromSync() should consume the
synchronous iterator instead of rejecting the input because it also
exposes an asynchronous or promise-like protocol.
Continue rejecting async-only iterables and promise/thenable-only
inputs, but allow sync iterables that also define Symbol.asyncIterator
or then().
