chore: combine some e2e tests to reduce the number of ucind clusters hence used system resources

* chore: update gitignore
* fix: create AAAA DNS record for IPv6 machines"
* test: randomize execution order to prevent order-based bugs in tests

+# AGENTS.md - Uncloud Project Guide
+
+This document provides comprehensive information about the Uncloud project for AI assistants to understand the codebase,
+architecture, and development practices.
+
+## Project Overview
+
+**Uncloud** is a lightweight clustering and container orchestration tool that enables deployment and management of web
+applications across cloud VMs and bare metal servers. It creates a secure WireGuard mesh network between Docker hosts
+and provides automatic service discovery, load balancing, HTTPS ingress, and simple CLI commands for application
+management.
+
+### Key Characteristics
+
+- **Language**: Go
+- **Architecture**: Decentralized, no control plane
+- **Target**: Self-hosted infrastructure without Kubernetes complexity
+- **License**: View LICENSE file for details
+- **Status**: Active development, not yet ready for production
+
+## Core Features
+
+### 🏗️ Infrastructure
+
+- **Multi-machine deployment**: Combine cloud VMs, dedicated servers, and bare metal
+- **Zero-config networking**: Automatic WireGuard mesh with NAT traversal
+- **Decentralized design**: No central control plane, all machines are equal
+- **Service discovery**: Built-in DNS server resolves service names to container IPs
+
+### 🚀 Application Management
+
+- **Docker Compose compatibility**: Uses familiar Docker Compose format
+- **Zero-downtime deployments**: Rolling updates without service interruption
+- **Automatic HTTPS**: Caddy reverse proxy with Let's Encrypt integration
+- **Managed DNS**: Free `*.xxxxxx.uncld.dev` subdomains via Uncloud DNS service
+- **Cross-machine scaling**: Run containers across multiple machines
+
+### 🔧 Developer Experience
+
+- **Docker-like CLI**: Familiar commands (`uc` binary)
+- **Imperative operations**: Direct commands vs. declarative state reconciliation
+- **Remote management**: Control entire infrastructure via SSH to any machine
+- **Minimal overhead**: ~150MB RAM footprint per machine
+
+## Architecture
+
+### Core Components
+
+1. **CLI (`uc`)** - Main user interface for cluster management
+2. **Daemon (`uncloudd`)** - Machine daemon running on each node
+3. **Corrosion** - Distributed SQLite database for cluster state (Fly.io project)
+4. **Caddy** - Reverse proxy for HTTPS termination and routing
+5. **WireGuard** - Secure mesh networking between machines
+
+### Network Architecture
+
+- Each machine gets unique subnet (e.g., `10.210.0.0/24`, `10.210.1.0/24`)
+- Containers get cluster-unique IPs for direct communication
+- Automatic peer discovery and key management
+- NAT traversal for machines behind firewalls
+
+### State Management
+
+- **CRDT-based distributed storage** using Corrosion
+- **Eventually consistent** state across all machines
+- **Gossip protocol** (Serf) for state propagation
+- **No quorum requirements** - partial network splits remain functional
+
+## Project Structure

+
+- **`experiment/`**: Experimental features and prototypes
+- **`scripts/`**: Installation and utility scripts

+- **`website/`**: Documentation website (Docusaurus)
+
+    - `landing/`: Landing page
+    - `docs/`: User documentation
+
+- **`misc/`**: Design documents and guides
+

+
+## Development Workflow
+
+### Build and Development
+
+```bash
+# Build binaries
+go build -o uncloud ./cmd/uncloud
+go build -o uncloudd ./cmd/uncloudd
+```
+
+### Key Make Targets
+
+- `proto`: Generate protobuf code
+- `ucind-cluster`: Create development cluster
+- `update-dev`: Deploy to development machines
+- `demo-reset`: Reset demo environment
+- `fmt`: Format code
+- `test`: Run all tests
+- `lint`: Lint the code using golangci-lint
+- `lint-and-fix`: Lint the code and fix issues whenever possible
+
+## CLI Commands Structure
+
+The `uc` CLI provides these main command groups:
+
+### Machine Management
+
+```bash
+uc machine init <user@host>     # Initialize new cluster
+uc machine add <user@host>      # Add machine to cluster
+uc machine ls                   # List machines
+uc machine rm <name>            # Remove machine
+```
+
+### Service Management
+
+```bash
+uc run <image>                  # Run container from image
+uc deploy                       # Deploy from compose.yaml
+uc scale <service> <count>      # Scale service replicas
+uc ls                           # List services
+uc rm <service>                 # Remove service
+```
+
+### Context and Connectivity
+
+```bash
+uc context ls                   # List available contexts
+uc context use <name>           # Switch context
+```
+
+### Global Flags
+
+- `--connect`: Connect to remote machine directly, without a config file
+- `--uncloud-config`: Override config file path
+
+## Development Guidelines
+
+### Code Organization
+
+- **Package naming**: Use clear, descriptive names
+- **Error handling**: Wrap errors with context using `fmt.Errorf`
+- **Logging**: Use structured logging with levels
+- **gRPC**: Services defined in `internal/machine/api/pb/`
+
+### Testing
+
+- Test files and locations
+    - Unit tests alongside source files (`*_test.go`)
+    - Integration tests in `test/e2e/`
+    - Test fixtures in `test/fixtures/`
+- Use table driven tests whenever possible
+
+### Dependencies
+
+- Prefer standard library when possible
+- Pin versions in `go.mod`
+- Document rationale for external dependencies
+
+### Configuration
+
+- Support environment variables for key settings
+- Validate configuration early
+- Provide sensible defaults
+
+## Troubleshooting and Debugging
+
+### Common Issues
+
+- **Networking**: Check WireGuard status, iptables rules
+- **DNS**: Verify service discovery resolution
+- **Containers**: Use standard Docker debugging tools
+- **State sync**: Check Corrosion logs for replication issues
+
+### Debugging Tools
+
+- Standard Linux networking tools (`ping`, `traceroute`, `wireshark`)
+- Docker commands (`docker ps`, `docker logs`)
+- SSH access to machines for direct inspection
+- gRPC debugging tools
+
+### Logs and Monitoring
+
+- Systemd services (getting logs via `journalctl -u SERVICE_NAME`)
+    - `uncloud` -- Uncloud daemon
+    - `uncloud-corrosion` -- Corrosion process
+- Machine daemon logs
+- Container logs via Docker
+
+## File Patterns and Conventions
+
+### Important Files to Understand
+
+- `cmd/uncloud/main.go`: CLI entry point and command structure
+- `internal/cli/cli.go`: CLI implementation and configuration
+- `internal/machine/machine.go`: Core machine management
+- `pkg/api/`: Public API definitions
+- `misc/design.md`: Architecture and design philosophy
+- `README.md`: Repository README
+
+### Configuration Files
+
+- `go.mod/go.sum`: Go dependency management
+- `Makefile`: Build and development tasks
+- `Dockerfile`: Container build instructions forUncloud-in-Docker (used for testing)
+
+This document should help AI assistants understand the project structure, make informed suggestions, and contribute
+effectively to the Uncloud codebase.
+
+## Documentation
+
+Instructions when generating documentation:
+
+- Use conversational language – write as if you were speaking to a friend.
+- Keep sentences simple, optimize for clarity and understanding.
+- Do not use em dashes (—) or semicolons (;) in sentences. Instead, break complex sentences into simpler ones.
+- Place the subject before the action whenever possible. Example: prefer "The function loads data" over "Data is loaded
+  by the function."
