• #10327 5dc11b5 Thanks @hntrl! - fix(core): replace exported zod type references with structural duck-type interfaces to fix TypeScript OOM

  Replaces all exported Zod type references (z3.ZodType, z4.$ZodType, etc.) in @langchain/core's public API with minimal structural ("duck-type") interfaces. This prevents TypeScript from performing expensive deep structural comparisons (~3,400+ lines of mutually recursive generics) when downstream packages resolve a different Zod version than @langchain/core, which was causing OOM crashes and unresponsive language servers in monorepo setups.

• #10433 7af0b65 Thanks @tanushree-sharma! - feat: Add LangSmith integration metadata to createAgent and initChatModel
