ci(showcase): add showcase-ops to deploy matrix for GHCR auto-rebuild

showcase-ops was excluded from .github/workflows/showcase_deploy.yml, so
commits touching showcase/ops/** never produced a fresh GHCR image. PR
CopilotKit#4293 (Status tab + /api/probes route) merged to main on 2026-04-26 but
no rebuild fired — the deployed Railway image is stale and /api/probes
404s in production.

Adding showcase-ops as a first-class matrix entry:
  - dispatch_name: showcase-ops (workflow_dispatch option + filter_key)
  - paths-filter: showcase/ops/**, plus shared/scripts/manifests
    (showcase-ops's Dockerfile bundles all four into the runtime image
    via build-stage COPY + generate-registry.ts)
  - context: '.' (repo root) so the Dockerfile can COPY from
    pnpm-workspace.yaml + packages/ + showcase/{ops,shared,packages,scripts}
  - dockerfile: showcase/ops/Dockerfile
  - image: showcase-ops -> ghcr.io/copilotkit/showcase-ops:latest
  - railway_id: 3a14bfed-0537-4d71-897b-7c593dca161d
  - health_path: /health (matches Dockerfile HEALTHCHECK + Hono route)
  - timeout: 20 (heavier build than shells: pnpm deploy + chromium
    install via playwright --with-deps)
  - lfs: false (no Git LFS assets in showcase/ops)
  - linux/amd64 platform inherited from existing build step (Depot)

Resulting matrix: 39 services (was 38). dispatch_name uniqueness +
JSON validity verified locally; actionlint/yamllint surface only
pre-existing findings on the workflow.
