Note

Medium Risk
Dependency-only change, but langchain jumps many versions and pulls in major upstream updates (e.g., openai v4), which can cause runtime or API-compatibility issues in the example.

Overview
Updates the langchainjs-localai-example dependencies to upgrade langchain from 0.0.67 to 0.0.141 (Snyk-driven security fix).

The lockfile is regenerated to reflect the new dependency graph, including newer transitive versions (notably openai v4 and updated @anthropic-ai/sdk) and additional packages required by the upgraded langchain.
