feat: add CI/CD workflow capabilities to code_ai_agent
Add Git, SSH, and K8s deploy tools enabling code_ai_agent to act as
an autonomous DevOps worker for the agent-manager project:
- tools/workspace.py: isolated /workspace/{task_id} per task
- tools/git_tools.py: clone, branch, status, write-file, commit-push
- tools/ssh_tools.py: SSH exec via paramiko (Azure VM support)
- tools/deploy_tools.py: K8s rollout restart/status via kubectl
- api_server.py: new routes /api/v1/git/*, /api/v1/ssh/*, /api/v1/deploy/k8s
- Dockerfile: add git, openssh-client, sshpass; pip install paramiko gitpython kubernetes
- requirements.txt: add paramiko, gitpython, kubernetes
