Michal 5e45960a18 feat: add Kubernetes orchestrator for MCP server pod management ...

mcpd can now deploy MCP server instances as Kubernetes pods instead of
Docker containers. Set MCPD_ORCHESTRATOR=kubernetes to enable.

- Add @kubernetes/client-node with thin wrapper (context enforcement
  via MCPD_K8S_CONTEXT to prevent multi-cluster mishaps)
- Rewrite KubernetesOrchestrator: pod CRUD, pod IP extraction,
  exec via SPDY (one-shot + interactive), log streaming
- Manifest generator: stdin:true for STDIO servers, args (not command)
  to preserve runner image entrypoint, security hardening
- Orchestrator selection in main.ts via MCPD_ORCHESTRATOR env var
- 25 unit tests for k8s orchestrator, all 624 tests pass

Tested end-to-end on local k3s:
- mcpd deployed via Pulumi, creates pods in mcpctl-servers namespace
- NetworkPolicy verified: only mcpd can reach MCP server pods
- Python runner (uvx) successfully runs aws-documentation-mcp-server
