feedback1 final: the boss-field speed test tolerates CI runners (1.0 ms with CI set, best of three runs; 0.5 ms locally)

test/sim/robustness.test.js "performance: heavy 2-player boss field" failed on GitHub's windows runners (0.51-0.58 ms
per tick against the 0.5 ms bar) on PR #10, PR #12, PR #14 and master's own push. The bar stays 0.5 ms on a development
machine and is 1.0 ms when process.env.CI is set (GitHub sets it); the measured time is the best of three runs of the
same battle after two warm-up battles, each run still checking the peak, the 18 operators and zero errors. Documented
in the test header, DESIGN §11 and the CHANGELOG's 工具 section.

 ### 工具
 
+- 领袖战性能测试在 CI（GitHub 的 Windows 机器较慢）上的门槛放宽到每帧 1.0 毫秒，并取三次运行中最快的一次；本地仍按 0.5 毫秒检查。
 - 素材下载有文件失败时，不再悄悄删掉 data/assets.json 里的条目，而是列出这些条目并保留原文件；确实要缩小时加 --allow-shrink（PR #7 指出）。
 
 ### 核实后不是问题
