[ Bounty $5k ] [ Deploy ] Add graceful queue pause before schema changes — maintenance release

[alex-huma-orch]

Bug Details

Affected component: maintenance deployment workflow.
Trigger: A release applies schema changes that affect task enqueue or dequeue operations.
Observed behavior: New tasks can be enqueued while migrations are changing related tables.
Expected behavior: Deployment can pause queue intake, drain safe work, run migration, then resume intake.
Impact: Tasks can be created with mixed schema assumptions during maintenance windows.

Fix

Add a controlled queue pause step with health messaging and automatic resume on successful migration.

Acceptance Criteria

• Maintenance deployments can pause and resume queue intake safely.
• Existing leased tasks follow the documented drain policy.
• Failed migrations leave intake paused only with an explicit operator alert.

🚀 Bounty Gate — Star First

You must star orchestration-agent/AgentOrchestration before submitting work. No star, no bounty. Simple.
