- sublet_1 的 T_LET 分支中，仅在后面还有 entries 时才遍历找尾 - s7_inlet 添加空参数快速路径，直接返回 make_let 性能变化（6000 slot 大 inlet，100 次迭代）： - copy big inlet: 0.0140s -> 0.0127s (-9%) - merge big inlet: 0.0119s -> 0.0105s (-12%) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
将各测试项运行时间控制在 0.01s ~ 1s 之间，减少测量噪声。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
在 inlet benchmark 中增加不同字段数量（2/4/16）的 record 创建、字段访问、类型判断及与直接 inlet 的对比测试。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Summary
优化
inlet函数在大 let 复制和合并场景下的性能。Changes
src/s7.c:sublet_1的T_LET分支中，添加if (is_pair(cdr(entries)))判断，避免append_let后对最后一个 let 进行不必要的二次遍历s7_inlet的空参数路径：当args == sc->nil时直接make_let返回，跳过sublet_1调用bench/inlet-bench.scm: 添加 inlet 性能 benchmarkdevel/0054.md: 添加开发文档Benchmark 结果（6000 slot 大 let，100 次迭代平均）
