Add an option to export/sync the local library to AniList or MyAnimeList

Describe your suggested feature

It would be useful to have an option that allows users to transfer their existing local CloudStream library to an external anime tracking service such as AniList or MyAnimeList.

For example, if a user already has anime saved in their CloudStream library under Watching, Completed, Plan to Watch, On Hold, or Dropped, CloudStream could allow them to export or sync these lists to their connected AniList or MyAnimeList account.

The feature could also transfer the user's current episode progress when possible.

This would be especially useful for users who have a large existing library and want to start using AniList or MyAnimeList without having to manually add every anime again.

Ideally, there could be an option such as:
"Import/Sync Local Library to AniList/MAL"

The existing local CloudStream library should remain unchanged after the transfer.

Other details

CloudStream already supports AniList/MyAnimeList tracking, but there does not seem to be an easy way to transfer an existing local library to these services.

Having a one-time migration option would make it much easier for existing users to move their library to an external tracking service.

It would also be useful if the feature could automatically match the anime in the local library with the correct AniList or MyAnimeList entries.

Acknowledgements

• My suggestion is NOT about adding a new provider
• I have searched the existing issues and this is a new ticket, NOT a duplicate or related to another open issue.

Start by locating CloudStream’s existing local library implementation and AniList/MyAnimeList tracking integration. Determine how library statuses, episode progress, account authentication, and anime matching are represented. Done means a one-time export or sync preserves the local library while transferring supported entries and progress to the selected external service.
