Implement BZZZ Phase 2A: Unified SLURP Architecture with Consensus Elections

🎯 Major architectural achievement: SLURP is now a specialized BZZZ agent with admin role

## Core Implementation:

### 1. Unified Architecture
- SLURP becomes admin-role BZZZ agent with master authority
- Single P2P network for all coordination (no separate systems)
- Distributed admin role with consensus-based failover

### 2. Role-Based Authority System (pkg/config/roles.go)
- Authority levels: master/decision/coordination/suggestion/read_only
- Admin role includes SLURP functionality (context curation, decision ingestion)
- Flexible role definitions via .ucxl/roles.yaml configuration
- Authority methods: CanDecryptRole(), CanMakeDecisions(), IsAdminRole()

### 3. Election System with Consensus (pkg/election/election.go)
- Election triggers: heartbeat timeout, discovery failure, split brain, quorum loss
- Leadership scoring: uptime, capabilities, resources, network quality
- Raft-based consensus algorithm for distributed coordination
- Split brain detection prevents multiple admin conflicts

### 4. Age Encryption Integration
- Role-based Age keypairs for content encryption
- Hierarchical access: admin can decrypt all roles, others limited by authority
- Shamir secret sharing foundation for admin key distribution (3/5 threshold)
- UCXL content encrypted by creator's role level

### 5. Security & Configuration
- Cluster security config with election timeouts and quorum requirements
- Audit logging for security events and key reconstruction
- Project-specific role definitions in .ucxl/roles.yaml
- Role-specific prompt templates in .ucxl/templates/

### 6. Main Application Integration (main.go)
- Election manager integrated into BZZZ startup process
- Admin callbacks for automatic SLURP enablement
- Heartbeat system for admin leadership maintenance
- Authority level display in startup information

## Benefits:
✅ High Availability: Any node can become admin via consensus
✅ Security: Age encryption + Shamir prevents single points of failure
✅ Flexibility: User-definable roles with granular authority
✅ Unified Architecture: Single P2P network for all coordination
✅ Automatic Failover: Elections triggered by multiple conditions

## Next Steps (Phase 2B):
- Age encryption implementation for UCXL content
- Shamir secret sharing key reconstruction algorithm
- DHT integration for distributed encrypted storage
- Decision publishing pipeline integration
