feat(cli): add listing-asset production to olares-publish skill (#3760)

* feat(cli): add listing-asset production to olares-publish skill

The skill specified what metadata.icon and spec.promoteImage[] must look
like but not how to produce them, so every run improvised a different
icon. Add the fetch/composite pipeline as reference docs plus two
executable helpers, and sort the market-ready requirements by whether
they actually block a merge.

The render pipeline composites the real screenshot back over the model
output: images/edits regenerates the whole canvas, so the model's version
of a UI is a reconstruction, which the skill's own rule against fabricated
UI forbids shipping.

* docs: correct the image host URL in the zh promote-apps guide

imghost.olares.cn does not resolve; only the .com host exists.
