Epic: close Dockerized runtime status

[smithaldon1]

Summary

• Closes Epic: Dockerized Factory Intelligence Platform microservices runtime #232.
• Updates current runtime/status docs so the Docker Compose path is described as the active local integration runtime instead of future placeholder work.
• Documents the implemented FIP service shape: API, Workbench, Postgres, read-only connector worker, Process Sentinel worker, and external Demo-Factory source fixture.
• Adds regression coverage that blocks stale placeholder and simulator-default wording from returning to current runtime docs.

Test Evidence

• PASS: .venv/bin/python -m pytest services/simulator/tests/test_runtime_docs_transition.py services/simulator/tests/test_docker_compose_runtime_docs.py
• PASS: docker compose -f infra/docker/docker-compose.yml config
• PASS: make lint
• PASS: make typecheck
• PASS: make test
• PASS: cd apps/web && npm test
• PASS: cd apps/web && npm run lint
• PASS: cd apps/web && npm run typecheck
• PASS: cd ../Demo-Factory && docker compose up -d --build
• PASS: make compose-smoke
  • services=5
  • events=260
  • detections=0
  • web_status=200
• Cleanup: docker compose -f infra/docker/docker-compose.yml down
• Cleanup: cd ../Demo-Factory && docker compose down

Docs Impact

• Updates README, development status, Docker runtime docs, demo runbook, Workbench README, ingestion README, and Workbench runtime notes.
• Adds a learning-log entry for the Dockerized runtime epic close-out.
• No API contract or service behavior changes.

Follow-Up Work

• Promote the Compose smoke path into CI once the local Docker/Demo-Factory runtime is stable enough for GitHub Actions.
• Keep any future connector expansion behind the read-only safety boundary.
