refactor(docker): optimize Docker build process and update configurations

- Replace direct Rust build with cargo-chef multi-stage build pattern
- Switch base image from debian:bookworm-slim to ubuntu:26.04
- Add .codegraph to .dockerignore and data to .gitignore
- Introduce Dockerfile.fast for faster builds without optimization
- Add comprehensive .env configuration file with cluster settings
- Create docker-compose.yaml for multi-node cluster setup
- Add cluster routing test case for distributed operations
- Remove unnecessary success status checks in repository maintenance
- Fix error handling in git command executions by properly propagating errors
- Add repository move protection to prevent self-destruct operations
- Simplify conditional logic in actor message validation
- Update remote pack client calls with proper error handling parameters
