Execution Lifecycle Manager

Centralized state management for running DAG executions with graceful shutdown patterns.

When to Use

✅ Use for:

• Implementing execution start/stop/pause/resume controls
• Graceful process termination (SIGTERM → SIGKILL)
• Tracking active executions across the system
• Cleaning up orphaned processes
• Implementing abort handlers with cost tracking

❌ NOT for:

• Cost estimation or pricing calculations (use cost-accrual-tracker)
• Building or modifying DAG structures
• Skill matching or selection
• Process spawning (use the executor directly)
