Background

ServiceWiring.php registers two services without the ReadingLists. namespace prefix that all other extension services use:

• ReverseInterwikiLookup (should be ReadingLists.ReverseInterwikiLookup)
• UserPreferenceBatchUpdater (should be ReadingLists.UserPreferenceBatchUpdater)

Unprefixed service names risk collision with identically-named services from other extensions and make it harder to audit which services belong to this extension.

Goal

Rename both service keys to include the ReadingLists. prefix and update all call sites.

Acceptance criteria for done

• Register ReadingLists.ReverseInterwikiLookup and ReadingLists.UserPreferenceBatchUpdater in ServiceWiring.php
• Update all getService() calls referencing the old names
