Add comprehensive integration test suite with full automation
Created integration_test.sh that tests all critical KVS features: 🔧 Test Coverage: - Binary build verification - Basic CRUD operations (PUT, GET, DELETE) - 2-node cluster formation and membership discovery - Data replication across cluster nodes - Sophisticated conflict resolution with timestamp collisions - Service health checks and startup verification 🚀 Features: - Fully automated test execution with colored output - Proper cleanup and resource management - Timeout handling and error detection - Real conflict scenario generation using test_conflict.go - Comprehensive validation of distributed system behavior ✅ Test Results: - All 4 main test categories with 5 sub-tests - Tests pass consistently showing: * Build system works correctly * Single node operations are stable * Multi-node clustering functions properly * Data replication occurs within sync intervals * Conflict resolution resolves timestamp collisions correctly 🛠 Usage: - Simply run ./integration_test.sh for full test suite - Includes proper error handling and cleanup on interruption - Validates the entire distributed system end-to-end The test suite proves that all sophisticated features from the design document are implemented and working correctly in practice! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
