Enhance notifications to avoid duplicates during auto search cycles

[Doezer]

This pull request improves notification logic for game availability and updates, ensuring users are only notified when new results become available (i.e., on a false→true transition), rather than on every search cycle. It also updates the UI to clarify notification behavior when preferred release groups are enabled, and adds comprehensive tests to verify deduplication and gating logic.

Notification deduplication and transition gating:

• Only send "Game Available", "Multiple Results Found", and "Game Updates Available" notifications when a game transitions from unavailable to available (false→true), preventing repeated notifications on subsequent cycles if the item remains available (server/cron.ts). [1] [2] [3] [4] [5]

Preferred release groups notification logic:

• Update UI help text to clarify that enabling preferred release groups will also limit notifications to only when a preferred group release is found (client/src/components/PreferredReleaseGroupsSettings.tsx).

Testing and verification:

• Add extensive tests to ensure notifications are deduplicated correctly, only sent on state transitions, and respect preferred release group settings (server/__tests__/cron_autosearch.test.ts).

Code Review

This pull request implements notification deduplication (transition gating) in the auto-search cron job, ensuring that availability and update notifications are only triggered on a false-to-true transition rather than on every cycle. It also updates the frontend settings description and adds comprehensive test coverage. Feedback points out a potential issue where the shared searchResultsAvailable flag is not reset when a game transitions from wanted to owned, which could cause users to miss the first update notification.
