…aling, and consensus tests

Implement four critical performance engineering issues:

Closes #317

• Performance Budgets:
• Add performance_budgets.toml with gas, size, and time budgets
• Create enforce_budgets.sh script for automated enforcement
• Integrate budget checks into CI/CD pipeline
• Define budgets for 30+ critical operations

Closes #321

• Performance Monitoring Dashboards:
• Create comprehensive Grafana dashboard with KPIs and trends
• Add 16 Prometheus alerting rules for proactive monitoring
• Monitor gas usage, consensus metrics, and budget compliance
• Include trend analysis and real-time visibility

Closes #322

• Automatic Scaling:

• Add load shedding with priority-based degradation
• Implement priority queuing for critical operations
• Add resource allocation based on load and priority
• Expose 9 public API functions for scaling control

Closes #324

• Property-Based Tests for Bridge Consensus:
• Add 9 comprehensive property tests for BFT validation
• Test Byzantine fault tolerance with 850+ test cases
• Validate quorum intersection and threshold monotonicity
• Cover edge cases for validator counts 1-10,000

Files changed:

• New: performance_budgets.toml, auto_scaling.rs, monitoring dashboard
• New: Prometheus alerting rules, budget enforcement script
