This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.

fix(sdk): keep SSE reconnect enabled with custom fetch

Auth/proxy fetch shims previously forced `maxReconnectAttempts: 0`, so
HITL waits that lost `/stream/events` (e.g. `ERR_QUIC_PROTOCOL_ERROR`)
never recovered and left `respond()`/`submit()` spinning. Fail-fast test
mocks should pass `maxReconnectAttempts: 0` explicitly. Also plumbs
reconnect options through framework `useStream` bindings.

- [#2602](https://github.com/langchain-ai/langgraphjs/pull/2602)
[`c201256`](https://github.com/langchain-ai/langgraphjs/commit/c201256b27d55c9aa333d3d15f6ec16c2fd7de9b)
Thanks [@HugoDurand](https://github.com/HugoDurand)! - fix(sdk): support
clearing a cron's end time via `crons.update(cronId, { endTime: null })`

`CronsClient.update` now accepts `endTime: null` to clear a previously
set cron end time; omitting `endTime` still leaves it unchanged. The
field was typed `string`, so callers could not express "clear" even
though the request already forwards an explicit `null`.
