 * Creates a logger that writes to stderr only.
 *
 * IMPORTANT: MCP uses stdio for JSON-RPC communication. The server sends
 * JSON responses over stdout, and the client parses them. Any non-JSON
 * output to stdout (like console.log) will corrupt the protocol and cause
 * parsing errors like "invalid character 'M' looking for beginning of value".
 *
 * All logging MUST go to stderr to avoid interfering with MCP communication.
