wrangler 4.93.1 捆的 workerd 构建于 2026-05-20，compat date 上限卡在 2026-05-27，而生产用的是 2026-07-20，本地没法跟生产同一口径。升级后 wrangler 内嵌 workerd 1.20260903.1，上限抬高，实测 2026-07-20 可正常启动。 三处对齐生产（生产配置由 `wrangler pages download config` 导出核对）： - compatibility_date 从 2024-04-01（那个废弃 toml 里的声明值）改为 2026-07-20 - 移除 compatibility_flags。生产未开 nodejs_compat，本地开着就比生产宽松， 某类只在生产炸的问题本地测不出来；项目代码不 import 任何 node: 内建模块， 去掉后 login / dns_templates / migrate_to_d1 三条路径实测正常 - 注释里把取值依据从「沿用旧 toml」改成「对齐面板导出」 顺带把 npm audit 的高危项从 10 降到 9（wrangler 依赖链上那条）。剩下的生产 依赖漏洞 js-yaml (high, 4.0.0-4.3.0) 与 dompurify (moderate) 不在本次范围内—— 上游 PR imzyb#471 正在修 js-yaml，等整合上游时一并处理。 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Summary
Upgrade js-yaml from 4.1.1 to 4.3.1, 3.15.1 to fix GHSA-5p4m-2wfm-xmqj.
Vulnerability
GHSA-5p4m-2wfm-xmqjpackage-lock.json(dependency:js-yaml)Description: JS-YAML: Quadratic CPU consumption in !!omap resolution (3.x and 4.x) — CVE-2026-59870 fix not backported

The change is scoped to 2 files on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.
This patch removes an exploit primitive — a code pattern that, while not independently exploitable today, could be chained with other weaknesses by automated exploit-development tooling. Proactive removal of such primitives raises the bar against increasingly capable automated attack tools.
