Add post-publish community save prompt

[laiyangjun-dotcom]

Summary

• Add a post-publish guidance prompt after a Xiaohongshu post is successfully published.
• Add A/B/C response handling for saving to community, optimizing the current plan, or skipping.
• Document best-effort session-recorder-skill integration with install checks and friendly failure handling.

Details

After scripts/xhs.sh publish succeeds and the post is recorded as published, ShuLing now prompts users to optionally save the successful plan as a reusable community template. The upload flow is intentionally best-effort and does not affect the Xiaohongshu publish result.

The reusable template guidance includes title, usage scenario, original request, final plan, Xiaohongshu title/body/tags, image prompt or generation parameters, publish time, and topic tags.

Testing

• Simulated A/a/存下来/上传社区 branch matching.
• Simulated B/b/再帮我优化一下/改改 branch matching.
• Simulated C/c/先不用/不上传 branch matching.
• Verified the documented endpoint uses https://cookbook-dev.omnieye.dev/api/solutions.
