[ArjinAlbay]

Section: Veri & Senkronizasyon
Component: src/stores/actionItems.ts
Priority: Critical

Details:

• The markAsRead(id) function should not only remove an item from the local list.
• If the item is a PR, it should also be closed on GitHub via a GraphQL Mutation or have a "Completed" comment added.

Impact:
Ensures consistency between the local app and GitHub.
