JSON-RPC helpers used by the MCP transport.
This module is intentionally small and focused on message shape detection, decoding, and standard protocol error payloads.
Examples
iex> MCPKit.Protocol.request?(%{"jsonrpc" => "2.0", "method" => "ping", "id" => 1})
true
iex> MCPKit.Protocol.success(1, %{"ok" => true})
%{"jsonrpc" => "2.0", "id" => 1, "result" => %{"ok" => true}}Summary
