feat: Implement complete CHORUS leader election system

Major milestone: CHORUS leader election is now fully functional!

## Key Features Implemented:

### 🗳️ Leader Election Core
- Fixed root cause: nodes now trigger elections when no admin exists
- Added randomized election delays to prevent simultaneous elections
- Implemented concurrent election prevention (only one election at a time)
- Added proper election state management and transitions

### 📡 Admin Discovery System
- Enhanced discovery requests with "WHOAMI" debug messages
- Fixed discovery responses to properly include current leader ID
- Added comprehensive discovery request/response logging
- Implemented admin confirmation from multiple sources

### 🔧 Configuration Improvements
- Increased discovery timeout from 3s to 15s for better reliability
- Added proper Docker Hub image deployment workflow
- Updated build process to use correct chorus-agent binary (not deprecated chorus)
- Added static compilation flags for Alpine Linux compatibility

### 🐛 Critical Fixes
- Fixed build process confusion between chorus vs chorus-agent binaries
- Added missing admin_election capability to enable leader elections
- Corrected discovery logic to handle zero admin responses
- Enhanced debugging with detailed state and timing information

## Current Operational Status:
✅ Admin Election: Working with proper consensus
✅ Heartbeat System: 15-second intervals from elected admin
✅ Discovery Protocol: Nodes can find and confirm current admin
✅ P2P Connectivity: 5+ connected peers with libp2p
✅ SLURP Functionality: Enabled on admin nodes
✅ BACKBEAT Integration: Tempo synchronization working
✅ Container Health: All health checks passing

## Technical Details:
- Election uses weighted scoring based on uptime, capabilities, and resources
- Randomized delays prevent election storms (30-45s wait periods)
- Discovery responses include current leader ID for network-wide consensus
- State management prevents multiple concurrent elections
- Enhanced logging provides full visibility into election process
