runners: add github-runner-updater Deployment

FlowerCore.Updater had only the offline bluejay-ws-sandbox-1 Windows
runner registered (the specialized fcsetup E2E target) and no Linux
self-hosted runner, leaving the repo with no Linux PR-CI capacity for
any future workflow. Modeled on github-runner-pimanager (Sprint 32
long-tail final entry, 2026-05-25); two replicas with per-pod emptyDir
caches to keep ReadWriteOnce PVC contention out of the picture.

Also registers github-runner-updater in the LinuxRunnerRepos +
ScaledLinuxRunnerDeployments fleet-lint sets so future suite repairs
treat the entry as canonically required (the 6 pre-existing lint
failures on this file family are orthogonal: initContainer single-
container count assertion + fc-updater IngressRoute POST allowlist
+ DM ApplicationSet convention drift).

 # 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).
