Move the LangChain and LangGraph gen-ai instrumentation from `@sentry/core` to
`@sentry/server-utils/src/ai/{langchain,langgraph}`, consuming the shared `ai/core`
base. The public helpers (`createLangChainCallbackHandler`, `instrumentLangChainEmbeddings`,
`instrumentStateGraph`, `instrumentStateGraphCompile`, `instrumentCreateReactAgent`) are
re-exported from `@sentry/server-utils` by node/cloudflare/vercel-edge, so the platform
SDK public API is unchanged.
LangChain and LangGraph move together because core's LangGraph imports functions and
types from LangChain (`createLangChainCallbackHandler`, `normalizeLangChainMessages`,
`_INTERNAL_mergeLangChainCallbackHandler`, `BaseChatModel`/`LangChainMessage`); splitting
them across PRs would require a temporary core->server-utils import (circular dep) or
duplicated code. Moving both keeps LangGraph on relative `../langchain` imports.
As with the other providers, `vercel-edge` re-exports from
`@sentry/server-utils/no-diagnostic-channels` to keep the edge build free of
`node:diagnostics_channel`.

This moves the LangChain and LangGraph integration core logic from
@sentry/coreto@sentry/server-utils, dropping all exports exceptcreateLangChainCallbackHandler,instrumentLangChainEmbeddings,instrumentStateGraph,instrumentStateGraphCompileandinstrumentCreateReactAgent. Moving these together because they have some interdependencies that make this a bit tedious otherwise.vercel-edgere-exportscreateLangChainCallbackHandler,instrumentLangChainEmbeddingsandinstrumentStateGraphfrom@sentry/server-utils/no-diagnostic-channelsto keep the edge build free ofnode:diagnostics_channel.
