"""Immortal Clone v2 - Enhanced with Victory Tracking, Progress Dashboard, Auto-Completion

Tier 1 Enhancements:
- CampaignVictoryTracker: Thread-safe shared VC state
- Auto-completion: Stop when all VCs met
- VC reporting: Explicit achievement logging
- Increased iteration limits: 200+ (configurable)

Tier 2 Enhancements:
- CampaignDashboard: Real-time progress with rich
- Progress callbacks: Clone iteration tracking
- Live updates: 2Hz refresh rate

Tier 3 Integration:
- War Room command hierarchy
- Campaign metrics tracking
- Progress tracker integration
- Army deployment patterns

Based on Geoff Huntley's insights + WhiteMagic's existing clone army infrastructure.
