Use sealos-skills to let DeepSeek Harness deploy projects to Sealos Cloud

sealos-skills is a DeepSeek Harness development and runtime plugin maintained by labring, which packages the deployment, database and object storage services of Sealos Cloud into a set of agent skills. The installation command on the catalog page is `dsh plugin add github:labring/sealos-skills`. The same skill source is also compatible with Claude Code, Codex and other tools. There is no `/sealos` slash command in DSH, and agents need to load the plugin through the skill tool before calling kubectl and sealos-cli.
