Patch Changes

• #10106 9f30267 Thanks @hntrl! - Add package version metadata to runnable traces. Each package now stamps its version in this.metadata.versions at construction time, making version info available in LangSmith trace metadata.

• #10154 403a99f Thanks @kanweiwei! - fix(core): add usage_metadata to AIMessage lc_aliases

• #10169 3b1fd54 Thanks @hntrl! - fix(core, langchain): bump uuid dependency from ^10.0.0 to ^11.0.0 to fix Metro bundler error

  The uuid v10 package has ambiguous exports in its package.json which causes Metro (used by Expo/React Native) to resolve the wrong entry point, resulting in Cannot read properties of undefined (reading 'v1'). The uuid v11 package fixes its exports map to work correctly with Metro's package exports resolution.

• #10044 77bd982 Thanks @hntrl! - fix(core): remove inherited LangChainTracer handlers when tracingEnabled is false

  When a RunTree explicitly disables tracing via tracingEnabled: false, CallbackManager._configureSync now strips any inherited LangChainTracer handlers so child runs don't produce traces.
