Initial release of the "jianying" skill:

- Registers the 剪映 (Jianying/CapCut) skill for organizing information from the official site, template center, features, help docs, and pricing.
- Focuses on public resources only—no private data handling, account actions, or premium resource downloads.
- Supports extraction of template types, editing features, export specs, help articles, and package details.
- Ensures all copyright or commercial-use notes retain original links; does not interpret or bypass restrictions.
- Prioritizes official sources for factual accuracy.
