perf: progressive loading for Cursor vscdb sessions - #125
Merged
Conversation
Load Cursor vscdb sessions in background (async execFile) instead of blocking the initial page load. Frontend auto-refreshes after 2 seconds when X-Loading header is present. Before: ~9.5s initial load (blocking) After: ~5.6s initial load + cursor sessions appear ~2s later - Workspace map cached to disk (10 min TTL) for fast subsequent loads - Background results merged into existing cache without full rebuild - X-Loading response header signals frontend to auto-refresh Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
