Sydney Runkle 7bb4130c7d chore(langchain): bump to 1.3.2, require langgraph>=1.2.2 (#37703) ...

- Bumps `langchain` to **1.3.2** (patch)
- Raises minimum `langgraph` requirement from `>=1.2.1` to `>=1.2.2`

langgraph 1.2.2 fixes a race condition where DeltaChannel checkpoint
writes
could serialize `BaseMessage` objects with `id=None` before
`apply_writes()`
ran the reducer, causing the same message to appear with a different ID
on
every `get_state()` call and across resumed invocations
(langchain-ai/langgraph#7913).

The lockfile will be updated once langgraph 1.2.2 is published to PyPI
(langchain-ai/langgraph#7914).
