Add Docker scripts and validation tests for Zen MCP Server
- Created build.sh script for building the Docker image with environment variable checks. - Added deploy.sh script for deploying the Zen MCP Server with health checks and logging. - Implemented healthcheck.py to verify server process, Python imports, log directory, and environment variables. - Developed comprehensive tests for Docker configuration, environment validation, and integration with MCP. - Included performance tests for Docker image size and startup time. - Added validation script tests to ensure proper Docker and MCP setup.
