Qwen patcher had two issues:
1. Only patched dashscope.aliyuncs.com but missed regional endpoints
(cn-hongkong, dashscope-intl, dashscope-us). Users in those regions
would still hit Aliyun directly.
2. --validate raised ModuleNotFoundError (referenced removed updater/
package). Replaced with self-contained inline checker — 13 GREEN
targets covering cli.js markers, settings.json, env vars.
Also bump Codex version to v0.122.0 across all READMEs (was v0.116.0).
