chore(deps-dev): bump @langchain/core from 1.1.46 to 1.2.3

[dependabot]

Bumps @langchain/core from 1.1.46 to 1.2.3.

Release notes

Sourced from @​langchain/core's releases.

@​langchain/core@​1.2.3

Patch Changes

• #11200 08e5888 Thanks @​hntrl! - fix(aws): normalize and safely replay Bedrock reasoning blocks

  Emit standard reasoning blocks with preserved signatures, omit incomplete signature-only reasoning during replay, and retain compatibility with legacy and redacted Bedrock reasoning.

@​langchain/core@​1.2.2

Patch Changes

• #11171 82bef01 Thanks @​christian-bromann! - fix(core): coerce string v1 AIMessage content to text blocks

  Prevent contentBlocks.push is not a function when constructing an AIMessage with response_metadata.output_version === "v1" and string content (common in serialized LangGraph stream payloads).

@​langchain/core@​1.2.1

Patch Changes

• #10674 f017708 Thanks @​christian-bromann! - fix: classify provider 429s before retrying

• #11092 7918bbd Thanks @​aolsenjazz! - fix(core): only treat arrays of content blocks as ToolMessage content

  Fix tool outputs that are arrays of plain objects being forwarded as malformed message content. An array is now only treated as message content blocks when every element is an object with a type; otherwise it is JSON-stringified.

@​langchain/core@​1.2.0

Minor Changes

• #10924 2e28115 Thanks @​christian-bromann! - feat(core): add OpenAI-compatible stream event conversion

Patch Changes

• #11047 ac0f71d Thanks @​christian-bromann! - fix(core): preserve AIMessage content blocks

  Keep existing v1 contentBlocks when constructing AIMessage instances so serialized messages do not lose block content during deserialization.

@​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.
