MCPRequestHandler.respond(to:emit:)

Answers one newline-delimited JSON-RPC request.

Returns the response line, or nil for a valid notification or an oversized request. Malformed JSON, invalid request objects, and request ids that cannot fit in a bounded response receive the standard JSON-RPC error with a null id.

• Parameters:
  • line: one JSON-RPC request without its trailing newline.
  • emit: where a notification sent *before* the answer goes — progress, while a long call is still running. Writing them is the caller's job because they share the one stdout the answer uses, and two writers there would interleave.
