Fixes: #64261

When some(), every(), or find() returns early, the underlying map() iterator closes but the source stream is never destroyed, leaving it open and preventing cleanup. The fix calls destroyImpl.destroyer(stream, null) in the map() iterator cleanup path so the source stream is destroyed when the iterator closes early.

Fixes: nodejs#64261

@Y1D7NG Can you please rebase?

The CI has been failing because of flaky tests which might have been marked/fixed in recent commits.
