feat: add K8s API server, orchestrator abstraction, and CI pipeline

- Add apps/api/ — Hono REST API server for managing pentest scans via K8s Jobs
  - POST/GET /api/scans, GET /api/scans/:id, cancel, report endpoints
  - Bearer token auth, Temporal client integration, K8s Job builder
  - Dockerfile, Kustomize manifests (Deployment, Service, RBAC)
- Add CLI orchestrator abstraction (docker.ts → Orchestrator interface)
  - DockerOrchestrator and K8sOrchestrator implementations
  - Backend detection via SHANNON_BACKEND env var or --backend flag
- Add CI workflow: type-check + lint on PR, build+push both images on main
- Switch all workflows to self-hosted runners (runners-farhoodliquor)
- Add shannon-api image build to release and release-beta workflows
- Add root infra/kustomization.yaml as Flux entry point
- Export PipelineProgress from @shannon/worker/pipeline
