feat(webiste): utiliziation cases of LLM frameworks.

[samchon]

This pull request primarily refactors the LangChain and MCP guide documentation pages to redirect users to their new locations under the /docs/utilization/ path, replacing the previous content with client-side redirects. Additionally, it introduces a reusable ClientRedirect React component for handling these redirects and updates some internal documentation links for consistency.

Documentation refactoring and redirects:

• Replaced the content of llm/langchain.mdx and llm/mcp.mdx with a <ClientRedirect> component that redirects to /docs/utilization/langchain and /docs/utilization/mcp, respectively, simplifying navigation and centralizing documentation. [1] [2]
• Added a new ClientRedirect React component in components/internal/ClientRedirect.tsx to handle client-side redirects and display a message to users.

Internal link updates:

• Updated the Swagger document link in llm/chat.mdx to use an external URL for clarity and consistency.
• Changed internal documentation links in llm/http.mdx to reference the new /docs/utilization/ paths for MCP and Vercel AI SDK.

Minor formatting:

• Added a newline at the end of _meta.ts for formatting consistency.
