/**
 * Database Cleanup Manager - Permanent Solution for Orphaned Database Connections

 * "unable to open database file" errors in WSL2 and Linux environments.
 *
 * Key Features:
 * - Automatic orphaned process detection
 * - Safe process termination with escalation
 * - PID lock file management
 * - WSL2-specific handling
 * - Graceful shutdown handlers
