feat(langchain): mark the `langchain.mcp` namespace as beta Importing from `langchain.mcp` now raises a `LangChainBetaWarning`, so a caller learns the API may still change at the moment they reach for it. Warned from the package body rather than through `@beta`, which annotates a function or class and so only fires once something is called. The status belongs to the namespace as a whole, and importing a submodule directly runs this module first, so both `from langchain.mcp import MCPAdapter` and `from langchain.mcp.elicitation import ...` are covered. `LangChainBetaWarning` subclasses `DeprecationWarning`, which Python mutes outside `__main__`, but importing `langchain_core._api` installs a `default` filter for it specifically, so it surfaces under stock settings. Tests pin that it fires, that it stays silenceable, and that the public names still export.
