fix(dev-env): update default OpenCloudOS image to 9.6-20260514.2 (9.4 download fails)

[husttsq]

问题

dev-env/ 下脚本默认的 OpenCloudOS 云镜像 9.4-20251120.0 在 mirrors.tencent.com 上已无法正常下载，导致拉取镜像失败。

改动

将以下两个脚本中默认 IMAGE_URL 升级为当前可用的最新镜像 9.6-20260514.2：

• dev-env/prepare_image.sh
• dev-env/run_vm.sh

-IMAGE_URL="${IMAGE_URL:-https://mirrors.tencent.com/opencloudos/9/images/qcow2/x86_64/OpenCloudOS-GenericCloud-9.4-20251120.0.x86_64.qcow2}"
+IMAGE_URL="${IMAGE_URL:-https://mirrors.tencent.com/opencloudos/9.6/images/qcow2/x86_64/20260514.2/OpenCloudOS-GenericCloud-9.6-20260514.2.x86_64.qcow2}"

PR Review: fix(dev-env): update default OpenCloudOS image to 9.6-20260514.2

Review Progress

• Read PR diff and changed files
• Verify the URL change is correct
• Check for other references to the old OpenCloudOS 9.4 image
• Update dev-env/run_vm.sh with the same URL change (needs author action — see below)
• Post final review summary

Review Summary

Change in dev-env/prepare_image.sh — Looks good ✅

The URL update is correct:

• Old: opencloudos/9/images/qcow2/x86_64/OpenCloudOS-GenericCloud-9.4-20251120.0.x86_64.qcow2
• New: opencloudos/9.6/images/qcow2/x86_64/20260514.2/OpenCloudOS-GenericCloud-9.6-20260514.2.x86_64.qcow2

The new URL structure (version directory 9.6 with a separate 20260514.2 build-timestamp subdirectory) matches OpenCloudOS 9.6's release layout. This is a straightforward, correct fix for the broken 9.4 download.

⚠️ Stale reference found in dev-env/run_vm.sh

There's a duplicate of the same default IMAGE_URL in dev-env/run_vm.sh at line 30 that still points to the old (broken) 9.4 image:

IMAGE_URL="${IMAGE_URL:-https://mirrors.tencent.com/opencloudos/9/images/qcow2/x86_64/OpenCloudOS-GenericCloud-9.4-20251120.0.x86_64.qcow2}"

This should also be updated to the new 9.6 URL for consistency — if someone runs run_vm.sh directly (without a pre-downloaded image or without setting IMAGE_URL), it would try to download the same broken 9.4 image.

Suggested fix:
Replace line 30 of dev-env/run_vm.sh with:

IMAGE_URL="${IMAGE_URL:-https://mirrors.tencent.com/opencloudos/9.6/images/qcow2/x86_64/20260514.2/OpenCloudOS-GenericCloud-9.6-20260514.2.x86_64.qcow2}"

Conclusion

The main change is correct and ready to merge. Consider also updating run_vm.sh to prevent a future download failure there as well.
