Fix several docstring inaccuracies in langchain-core and update outdated LangSmith URLs across three README files. **Docstring fixes (libs/core):** - `tap_output_iter`: docstring says "async iterator" but method accepts sync `Iterator` - `agenerate_from_stream`: docstring says "Iterator" but method accepts `AsyncIterator` - `BaseLLM.OutputType`: docstring says "input type" but property returns output type - Grammar: "or deprecated" → "or be deprecated", "relies" → "rely", "whose the" → "whose" **URL fixes (libs/core, libs/langchain, libs/langchain_v1):** - Updated `smith.langchain.com` → `www.langchain.com/langsmith` (root README already uses the correct URL) Verified with `make lint` and `make format` in libs/core — no new issues introduced. Changes are docs-only with no code logic impact. *This PR was created with assistance from an AI coding tool.*
