The v0.6.8 release contains AppImages for both Linux architectures but no .AppImage.zsync files, and its AppImage runtime reports empty update information. Gear Lever/AppImageUpdate therefore cannot automatically discover updates. Both the Actions artifact paths and the GitHub Release asset filter also exclude zsync sidecars.

Embed an architecture-specific gh-releases-zsync locator for the current repository's latest stable release, install zsync, and regenerate the sidecars after the existing icon/permission repair step so their checksums match the final AppImages. Include sidecars in both artifact uploads and Release publication. Add a brief note to the English and Chinese build guides, including the one-time manual replacement needed for older AppImages.

Validation:

• actionlint and git diff --check pass.
• Built a small real x86_64 AppImage with linuxdeploy's AppImage plugin, forced the existing permission repair, and ran the new workflow step. Embedded update information survived the repair; zsync reconstruction verified the resulting checksum and matched the final image byte for byte. An incorrect embedded locator was rejected.
• Locally simulated both Release creation and update with a mocked gh, confirming both architectures' .AppImage.zsync files are selected for upload.
• Existing AppImage metadata/permission regression suite: all 20 cases pass.

No new test files or CI jobs are included. Full application release builds and native ARM64 packaging were not run locally.

已审核 09c8e258，暂未发现阻塞问题。原先没有 checks 是 fork 工作流等待批准，本次已批准运行 CI。

本轮验证：workflow 的 actionlint 静态检查、git diff --check、现有 20 项 AppImage 图标/权限回归均通过；另在 Linux 环境独立验证真实 x86_64 AppImage 的更新信息嵌入、修复后保留、最终 zsync 重建字节一致性和错误架构地址拒绝；Release 创建/更新两条路径均正确选取两种架构的 sidecar，保留原有 portable ZIP。

本次 4 项 CI 已全部通过，已 squash 合并为 452eef5d；合并前也确认与侧栏修复后的最新主线无冲突。完整 Linux 应用 release 构建及原生 ARM64 打包未在本轮执行，仍需在后续发布流程验证。
