Move all save_json/load_json/sync_to_db/DB calls off the event loop with asyncio.to_thread to prevent UI freezes. Cache graphviz SVG by DOT source hash (bounded LRU of 20). Replace DELETE-all/re-INSERT in sync_to_db with UPSERT + targeted DELETE. Add DB indexes, COUNT query, and reduce graph poll interval to 0.5s. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
