Track Specification: Pipeline Pause/Resume (pipeline_pause_resume_20260306)

Overview

Add global pause/resume for entire DAG execution pipeline. Allow user to freeze all worker activity and resume later.

Architectural Constraints

• State Preservation: Worker state MUST be preserved across pause.
• Atomic Operation: Pause/Resume MUST be atomic.

Functional Requirements

• Pause Button: Freeze all worker activity.
• Resume Button: Continue from paused state.
• Visual Indicator: Show pipeline is paused.
• State Display: Show which workers are paused.

Acceptance Criteria

• Pause button freezes pipeline.
• Resume button continues execution.
• Visual indicator shows paused state.
• Worker states preserved.
• No data loss on resume.
