Atomic task locking — one agent per task, no double-work.
Prevent two agents from working on the same task simultaneously. When an agent selects a task, it must check it out first. The checkout is atomic: if two agents race for the same task, exactly one wins and the other gets a 409 Conflict. Locks auto-release on agent death (detected via heartbeat), explicit release, or timeout.
# Check out a task
/checkout task-d4e5
# Check out with explicit timeout
/checkout task-d4e5 --timeout 30m

# Force-release (admin override)
/checkout release task-d4e5 --force
# List all active checkouts
/checkout list
# Check if a task is locked
