Add security remediation infrastructure and fixes 

Implement comprehensive security infrastructure from Security-Remediation-Plan.md:

New Infrastructure Files:
- circuit_breaker.go (ARCH-001): Circuit breaker pattern for contract failures
  with Closed/Open/Half-Open state machine and emergency shutdown
- invariants.go (ARCH-003): Formal verification with 14 critical invariants
  and TLA+ specifications for runtime verification
- canary_deployment.go (ARCH-004): Feature flags with percentage-based rollout
  and auto-rollback on error rate threshold
- audit_logger.go (ARCH-005): Comprehensive audit logging with multi-index
  querying across 8 categories (Auth, Access, Data, Governance, etc.)
- config_registry.go (LOW-003): Configuration governance infrastructure
- event_archival.go (LOW-001): Event log archival with Merkle commitments
- validation.go (LOW-002): Common input validation constants and utilities
- role_registry_domain.go (CRIT-002): Domain-specific committee roles
  (Legal, Health, Education, Economy, Identity, Governance)

Contract Security Fixes:
- contract.go: Add HasDomainCommitteeAuthority to IRoleRegistry interface
- lex.go: Remove duplicate ErrReasonTooLong declaration
- salus.go, eligere.go, palam.go, pons.go, scire.go, tribute.go:
  Line ending normalization and security validation integration
- collocatio.go: Security validation for investment operations

State Type Updates:
- state/pons.go, state/salus.go, state/tribute.go: Line ending fixes
