build(deps): bump langchain from 0.3.33 to 1.5.0 in /archive/server_old

[dependabot]

Bumps langchain from 0.3.33 to 1.5.0.

Release notes

Sourced from langchain's releases.

langchain@1.5.0

Minor Changes

• #11062 3ebd10a Thanks @​christian-bromann! - feat(langchain): surface tool-dispatched subagents on run.subagents

  Add a native subagent stream transformer to createAgent so v3 runs expose named nested agents (createAgent({ name }) invoked from tools) as typed SubagentRunStream handles with name, cause, scoped messages / toolCalls, and output. Refactors agent stream transformers into agents/transformers/ and exports only the public stream types from the package entry.

langchain@1.4.6

Patch Changes

• #11012 4aeaa76 Thanks @​christian-bromann! - feat(langchain): add when predicate to human-in-the-loop middleware

  Add an optional when callback on InterruptOnConfig so callers can dynamically skip interrupts for specific tool calls. The predicate receives a ToolCallRequest (batch afterModel context) and returns whether to interrupt or auto-approve, matching Python HumanInTheLoopMiddleware.

• #11080 e51478a Thanks @​aolsenjazz! - feat(aws): bedrock prompt caching middleware

  Adds bedrockPromptCachingMiddleware. The interface largely matches what was previous implemented with anthropicPromptCachingMiddleware, making a best-effort attempt at utilizing prompt caching features for supported models.

langchain@1.4.2

Patch Changes

• #10900 6bbddca Thanks @​christian-bromann! - fix(langchain): unwrap tool message outputs in agent streams

• #10706 4ecb660 Thanks @​JadenKim-dev! - fix(langchain): set name on todoListMiddleware ToolMessages

langchain@1.4.1

Patch Changes

• #10879 eb480cb Thanks @​vignesh-gep! - fix(langchain/createAgent): throw on terminal providerStrategy parse failure instead of silently resolving with structuredResponse: undefined

  When createAgent was configured with responseFormat resolving to a providerStrategy (either passed explicitly or auto-promoted from a bare Zod / JSON schema for models whose profile reports structuredOutput: true), and the model produced a terminal response (no tool_calls) whose text could not be JSON-parsed or did not satisfy the schema, the agent silently exited with no structuredResponse, surfacing later as TypeError: Cannot read properties of undefined. The agent now throws a StructuredOutputParsingError in that case while still allowing the agent loop to continue when tool calls are present. Closes #10878.

• #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.

• #10160 bba900c Thanks @​JadenKim-dev! - fix(langchain): prevent llmToolSelectorMiddleware from leaking into message stream

langchain@1.3.4

Patch Changes

• #10713 49ac9e7 Thanks @​jacoblee93! - feat(langchain): Adds ls_agent_type to create agent runs as tracing metadata
