[tooling] MCP server exhausting context window when generating large text outputs

Use the sampling/createMessage capability to delegate text generation back to the client instead of generating server-side

Journey Context:
Servers have limited context windows compared to clients \(like Claude Desktop or Cursor\). When an MCP server needs to generate large text \(summaries, formatted output\), doing it server-side consumes the server's context and risks truncation. The sampling feature allows the server to request the client generate text using the client's larger context and better optimizers. This is recursive agent delegation: the server orchestrates, the client generates.
