`ReadableStream.cancel()` adopts the underlying source's cancel promise,
which is permitted never to settle — so awaiting `releaseBody` while
propagating a cancellation can hang the very thing it was meant to end.
The five exceptional exits in the compat probe loop now start the
release without waiting on it: the release is a courtesy to the
connection pool, and the caller's abort or timeout must reach it
regardless. The two non-exceptional awaits are unchanged.
Same class as the tee teardown in round 24, one file over.
Also moves the `redactUrlQuery` import above
DEFAULT_OAUTH_REQUEST_TIMEOUT_MS's JSDoc, which it had split from the
constant — so hover and API tooling see the doc again.
Verified by mutation: awaiting the release makes the new test time out.
