runners: add github-runner Deployments for DeviceManagement + AiStation.Linux + WorldBuilder

Morning-routine 2026-05-26 — these three repos had ZERO online Linux PR-CI
capacity, blocking the Sprint 37 Cx-1 Linux-CI-migration PRs (DM #20/#21/
#22, AiStation.Linux #13, WorldBuilder #3/#4). Chicken-and-egg: the
migration PRs need Linux runners that the migration creates.

Each Deployment uses the same canonical emptyDir-only pattern as the
fresh-2026-05-26 updater deployment that lives just above:
  - replicas: 2 (room for parallel PR-CI without head-of-line blocking)
  - per-pod emptyDir caches (no RWO PVC contention)
  - shared github-runner-token secret (existing ACCESS_TOKEN PAT has
    org-wide read access)
  - LABELS: self-hosted,linux,fc-build-linux
  - DOTNET_INSTALL_DIR pinned per ADR-170 family

For AiStation.Linux specifically: Linux job will now pick up; the
Windows job in #13 remains queued indefinitely until the Windows runner
host substrate lands per Sprint 36 v2 Cl-2 / ADR-174 — that's a separate
arc, not this PR.

 # Long-tail runner pattern:

 # Sprint 32 added the final 16 long-tail repo-scoped Deployments above. Keep
 # Common as the only PVC-backed runner at replicas: 1. Any future multi-replica
 # runner must use per-pod emptyDir caches, not a shared ReadWriteOnce PVC.
+# 2026-05-25: PiManager added (was missed in the Sprint 32 long-tail sweep).
+# 2026-05-26: Updater + DeviceManagement + AiStation.Linux + WorldBuilder
+# added by the morning-routine sweep — those repos had had ZERO online Linux
+# PR-CI capacity, blocking the Sprint 37 Cx-1 Linux-CI-migration PRs.
