The autocomplete menu for wiki-links was opening immediately on typing '[[', processing all 9000+ vault entries and causing a visible freeze. - 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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
