fix(api): prevent duplicate feed and search requests

Add concurrency guards to prevent duplicate API requests when
methods are called multiple times before completion.

- HomeView.updateAllFeed(): guard against concurrent calls with
  retry count limit to prevent infinite recursion
- DiscoverView.searchAll(): guard initial searches while allowing
  concurrent pagination
- DiscoverView.searchStarred(): guard against concurrent calls

These changes prevent duplicate network requests while preserving
legitimate concurrent pagination behavior.
