题目说明
编写 function solution(documents, query, limit)。输入输出均为 JSON 值，不要修改输入数组或对象。不支持外部库、网络访问及异步函数。 documents:{id:string,vector:integer[]}[], query:integer[], limit:nonnegative integer. Vectors share dimension 1–32 with values -100…100. Cosine=dot/(product of magnitudes); use zero if either vector is zero. score=Math.round(cosine*1_000_000). Sort by rounded score descending, preserving input order on ties. Return top limit {id,score}; limit may exceed document count. 输入范围：每个输入数组最多50,000项，每个字符串最多1,000个字符。数字必须有限，整数及整数累计结果在JavaScript安全整数范围内。其他类型和有效性遵循上述规则。
