This release resolves critical database lock issues and adds comprehensive hybrid backend support to the installer.

🎯 Key Improvements

✅ Zero Database Locks - Proper SQLite pragma configuration eliminates "database is locked" errors
✅ Hybrid Backend Default - Fast local SQLite (5ms) + background Cloudflare sync
✅ Auto-Configuration - Installer handles SQLite pragmas (busy_timeout=15000,cache_size=20000)
✅ Interactive Setup - Cloudflare credential configuration with connection testing
✅ Graceful Fallback - Falls back to sqlite_vec if cloud setup fails

🔧 Fixes

• Database Lock Prevention: Resolved "database is locked" errors during concurrent HTTP + MCP server access
  • Root cause: Default busy_timeout=5000ms too short for concurrent writes
  • Solution: Applied recommended SQLite pragmas
  • Impact: 5/5 concurrent writes succeeded without locks
  • WAL mode properly configured for multi-client operations

✨ New Features

• Full Hybrid Backend Support in simplified installer
• Automatic Claude Desktop Configuration with:
  • SQLite pragmas for concurrent access
  • Cloudflare credentials for background sync
  • Proper environment variable propagation
