chore(deps): bump the patch-updates group with 2 updates

[dependabot]

Bumps the patch-updates group with 2 updates: @langchain/core and langchain.

Updates @langchain/core from 1.1.47 to 1.1.48

Release notes

Sourced from @​langchain/core's releases.

@​langchain/core@​1.1.48

Patch Changes

• #10832 1b24369 Thanks @​info-arnav! - fix(core, openrouter): make CJS default re-exports callable

• #10666 2bb55b0 Thanks @​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.
