Fix memory exhaustion in MCP server chaos tests
Resolved "Worker terminated due to reaching memory limit" errors by: - Increased Node.js heap size to 4GB via NODE_OPTIONS - Extended test timeout from 5000ms to 30000ms for chaos tests - Configured Vitest to use forked processes with proper isolation This prevents memory leaks between test runs and allows resource-intensive chaos tests to complete successfully.
