chore(deps): bump uuid and @langchain/core

[dependabot]

Removes uuid. It's no longer used after updating ancestor dependency @langchain/core. These dependencies need to be updated together.

Removes uuid

Updates @langchain/core from 1.1.38 to 1.1.49

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.

• #10918 3999fab Thanks @​christian-bromann! - fix(openai): stream custom tool calls through Responses API chunks

@​langchain/core@​1.1.47

Patch Changes

• #10906 f61b345 Thanks @​hntrl! - feat(core): add uuid v6 utility support

  Add v6 UUID generation support to @langchain/core/utils/uuid by vendoring the upstream uuidjs v6 implementation and its v1ToV6 helper, exporting v6 from the UUID utils index, and adding tests for deterministic generation, buffer/offset behavior, validation/versioning, and ordering.

• #10872 a640079 Thanks @​hntrl! - chore(deps): remove redundant @​types/uuid declarations

  Remove @types/uuid from package manifests that rely on @langchain/core/utils/uuid or do not require uuid type stubs directly, and refresh the lockfile entries accordingly.

• #10792 3682268 Thanks @​Genmin! - fix(core): apply v1 message casting after implicit streaming aggregation

• #10901 f26fc4a Thanks @​christian-bromann! - fix(testing): share fakeModel invocation state across bindTools instances

@​langchain/core@​1.1.46

Patch Changes

• #10847 1659e7d Thanks @​hntrl! - chore(core): reduce transitive dependency exposure and tighten release hygiene

  Remove direct runtime dependencies on ansi-styles, camelcase, and decamelize by inlining equivalent logic in core internals, and enable npm provenance in the release workflow.

• #10790 ef78bc6 Thanks @​Genmin! - fix(core): keep different content block types separate when merging chunks
