feat: Implement Multi-Party Fee Distribution System with Governance

[Jagadeeshftw]

🎯 Overview

This PR implements a comprehensive multi-party fee distribution system that moves beyond the current single admin address model to support configurable fee distribution among multiple parties with governance capabilities.

✨ Key Features Added

Core Fee Distribution

• distribute_fees_to_parties() - Distributes collected fees to multiple recipient addresses based on configurable percentages
• validate_fee_dist_percentages() - Validates that distribution percentages sum to 100%
• validate_distribution_totals() - Ensures distribution amounts match collected fees

Configuration Management

• get_fee_distribution_config() - Retrieves current fee distribution configuration
• update_fee_distribution_config() - Allows admins to update distribution settings
• FeeDistributionConfig - New struct managing recipient addresses, percentages, and governance settings

Tracking & Analytics

• track_fee_distribution_history() - Retrieves historical distribution records for markets
• FeeDistributionExecution - Records individual fee distribution events with recipient breakdowns
• FeeDistributionAnalytics - Provides aggregated statistics on fee distribution performance

Governance System

• create_distribution_proposal() - Creates governance proposals for fee distribution changes
• vote_on_distribution_proposal() - Allows voting on proposed distribution changes
• execute_governance_proposal() - Executes approved governance proposals
• FeeDistributionGovernance - Manages proposal lifecycle and voting mechanisms

Event System

• emit_fee_distribution_event() - Emits events for transparency and off-chain tracking
• Enhanced event emission for fee distribution activities, governance proposals, and configuration updates

🏗️ Technical Implementation

New Data Structures

// Core configuration for fee distribution
pub struct FeeDistributionConfig {
    pub distribution: Map<Address, i128>,  // address -> percentage
    pub total_percentage: i128,
    pub governance_enabled: bool,
    pub community_participation: bool,
    // ... additional fields
}

// Records individual distribution executions
pub struct FeeDistributionExecution {
    pub market_id: Symbol,
    pub total_amount: i128,
    pub distribution: Map<Address, i128>,
    pub timestamp: u64,
    // ... additional fields
}

// Manages governance proposals
pub struct FeeDistributionGovernance {
    pub proposal_id: u64,
    pub proposed_config: FeeDistributionConfig,
    pub votes: Map<Address, bool>,
    // ... additional fields
}

Enhanced FeeManager

• Renamed to FeeDistributionManager for clarity
• Added comprehensive fee distribution logic
• Integrated with existing MarketStateManager, FeeValidator, and EventEmitter
• Persistent storage for configurations, history, and governance data

🔧 Configuration Options

• Minimum/Maximum Distribution Percentages - Configurable limits per recipient
• Governance Participation - Enable/disable community voting on distribution changes
• Community Participation - Allow broader participation in fee distribution
• Distribution Names - Human-readable configuration identifiers

📊 Analytics & Monitoring

• Historical Tracking - Complete audit trail of all fee distributions
• Performance Metrics - Efficiency calculations and top recipient identification
• Governance Analytics - Proposal success rates and voting patterns

🛡️ Security & Validation

• Percentage Validation - Ensures distribution percentages sum to 100%
• Amount Validation - Verifies distribution amounts match collected fees
• Admin Authorization - Proper access controls for configuration updates
• Governance Verification - Multi-step approval process for major changes

🧪 Testing

• All existing tests pass (cargo test successful)
• New fee distribution functionality thoroughly tested
• Governance mechanisms validated
• Event emission verified

⚠️ Breaking Changes

• None - this is a purely additive feature
• Existing single admin fee collection remains functional
• Backward compatibility maintained

🚀 Migration Path

1. Deploy contract with new fee distribution system
2. Configure initial multi-party distribution via update_fee_distribution_config()
3. Begin using distribute_fees_to_parties() for new markets
4. Optional: Enable governance for community participation

🔮 Future Enhancements

• Advanced governance mechanisms (time-locks, multi-sig)
• Dynamic fee distribution based on market performance
• Integration with external governance platforms
• Enhanced analytics dashboard integration
