- Extract preFilterWikilinks utility with MIN_QUERY_LENGTH=2 gate
- Pre-filter entries with case-insensitive substring match before
creating expensive onItemClick closures
- Cap results at MAX_RESULTS=20 after BlockNote's filterSuggestionItems
- Add comprehensive tests for the utility and Editor integration
