chore: version packages (#10919)

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.


# Releases
## @langchain/mistralai@1.1.0

### Minor Changes

- [#10873](#10873)
[`a74d574`](a74d574)
Thanks [@baptistejamin](https://github.com/baptistejamin)! -
chore(mistralai): upgrade to @mistralai/mistralai v2

Also populates `response_metadata.model` on chat completions (was
missing before).

## @langchain/openrouter@0.3.0

### Minor Changes

- [#10666](#10666)
[`2bb55b0`](2bb55b0)
Thanks [@hnustwjj](https://github.com/hnustwjj)! - feat(openrouter):
surface reasoning content as v1 standard content blocks

    `convertOpenRouterResponseToBaseMessage` and
    `convertOpenRouterDeltaToBaseMessageChunk` now copy OpenRouter's
`reasoning` (flat string) and `reasoning_details` (structured array)
fields
onto `additional_kwargs.reasoning_content` /
`additional_kwargs.reasoning_details`.
A new `ChatOpenRouterTranslator` is registered in `@langchain/core`
under
the `"openrouter"` provider key so `AIMessage.contentBlocks` emits
standard
    `{type: "reasoning"}` blocks alongside text and tool calls.

Previously, reasoning text returned by reasoning-capable models routed
through OpenRouter (DeepSeek R1, Minimax M2, Claude extended thinking,
o-series, etc.) was silently dropped: only the `reasoning_tokens` count
was preserved via `usage_metadata`. Consumers using standard content
blocks
(including the frontend agent UI patterns shown in the docs) could not
    display the model's chain of thought.
