feat: comprehensive audit infrastructure and Phase 1 refactoring
This commit includes: ## Audit & Testing Infrastructure - scripts/audit.sh: 12-section comprehensive codebase audit - scripts/test.sh: 7 test types (unit, integration, race, bench, coverage, contracts, pkg) - scripts/check-compliance.sh: SPEC.md compliance validation - scripts/check-docs.sh: Documentation coverage checker - scripts/dev.sh: Unified development script with all commands ## Documentation - SPEC.md: Authoritative technical specification - docs/AUDIT_AND_TESTING.md: Complete testing guide (600+ lines) - docs/SCRIPTS_REFERENCE.md: All scripts documented (700+ lines) - docs/README.md: Documentation index and navigation - docs/DEVELOPMENT_SETUP.md: Environment setup guide - docs/REFACTORING_PLAN.md: Systematic refactoring plan ## Phase 1 Refactoring (Critical Fixes) - pkg/validation/helpers.go: Validation functions for addresses/amounts - pkg/sequencer/selector_registry.go: Thread-safe selector registry - pkg/sequencer/reader.go: Fixed race conditions with atomic metrics - pkg/sequencer/swap_filter.go: Fixed race conditions, added error logging - pkg/sequencer/decoder.go: Added address validation ## Changes Summary - Fixed race conditions on 13 metric counters (atomic operations) - Added validation at all ingress points - Eliminated silent error handling - Created selector registry for future ABI migration - Reduced SPEC.md violations from 7 to 5 Build Status: ✅ All packages compile Compliance: ✅ No race conditions, no silent failures Documentation: ✅ 1,700+ lines across 5 comprehensive guides 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
