enhance: add comprehensive resilience to CI deployment script - Concurrent execution prevention with lock files - Retry logic for transient failures (3 attempts) - Extensive pre-flight checks (disk space, env vars, Docker health) - Configurable timeouts (5min deployment, 2min health checks) - Enhanced health checking with multiple validation methods - Automatic cleanup on script exit - Detailed debugging information on failure - Environment variable validation for all 10 secrets - Rollback preparation and improved logging
